So you started your startup — now how do you find a great product ASAP? At our startup, Granola, we rapidly _evolved_ a product using principles from natural selection! We made our software friendly to _mutation_ by using repetitive code, all in one blob, with no tests. For parallel _selection_ of the best variants, we manually sent programs to target users. And to make our variants friendly to _extinction_, we avoided all launches, landing pages, and docs. Beware: big-company "best practices" make bad early-stage startups!
## The greatest startup story of all time
<figure>
<img style="max-width: 20em; float: right;" src="https://www.granola.so/blogImages/evolve/1_pikaia.avif" alt="Pikaia" />
<figcaption>
<i>Pikaia (early screenshot)</i>
</figcaption>
</figure>
This guy is _Pikaia_. He lived around 500 million years ago, grew to around 4cm long, and perhaps swam like an eel. Shortly after, along with most other species, he disappeared.
<figure className="not-prose left">
<img src="https://www.granola.so/blogImages/evolve/2_pioneer.avif" alt="Pioneer plaque" />
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Pikaia sapiens?</i>
</figcaption>
</figure>
And yet _Pikaia_ lives on: his descendants are you and me, rulers of this planet, with influence even beyond the solar system, their images engraved forever on the Pioneer spacecrafts! I believe **the Cambrian explosion is the best startup story of all time**, full of rapid prototyping and forgotten pivots! Like our early-stage startup, natural selection is a search for new, better designs in a shifting landscape.
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/3_pigeons.avif" alt="Pigeons" />
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Victorian hackathons</i>
</figcaption>
</figure>
Some believe that evolution has to be _slow_, but that's just false. Darwin's theory was influenced by pigeon breeders, who were able to find wonderful new pigeon designs within strikingly short time periods. I like to think of good startups like these breeders: tastefully using **mutation** and **selection** to find wonderful new products. My claim: when designing startups, we can draw surprisingly concrete lessons from how natural selection works! For my first example: let's look at nature's attitude toward copy-paste.
## Avoid abstractions. Use copy-paste-edit!
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/4_williston.avif" alt="Williston's law" />
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Fun fact: the snake went full circle.</i>
</figcaption>
</figure>
How did your arms and legs come to be? Notice a difference between you and _Pikaia_: _Pikaia_ has lots of repeated segments, but your body has just a few specialized segments. This happens so often in evolution that it has a name: it’s called Williston’s Law. Roughly, it says that **nature loves to copy-paste and edit.** Nature takes a versatile body part like a leg or a tooth, duplicates it many times, gives each one a chance to specialize, then kills off the excess.
<figure className="not-prose left">
<img
src="https://www.granola.so/blogImages/evolve/4_hox_tree.avif"
alt="Hox gene evolutionary tree"
/>
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>The more Hox genes you paste, the more shapes you can make!</i>
</figcaption>
</figure>
Nature's love of copy-paste can be seen genetically as well. When you were still an embryo, your body plan was drawn out by 39 different "Hox" genes. Each Hox gene corresponds to one part of your body. But our early ancestors had just one Hox gene! Nature then copy-pasted and edited it many times, and now we have 39 of them, each with a different function. In Computer Science courses, they gave us clear, static requirements, and we were supposed to implement these with "clean code". But **programs designed for certain, static requirements look very different to programs designed for uncertainty and change!**
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/4_copy_paste_edit.avif" alt="Copy-paste-edit" />
</figure>
Say you want to add a new kind of "big button" component. Instead of introducing an abstract "button" concept, try duplicating the existing button component, and allowing it to evolve along its own path. Even if your "button" abstraction is _right_ under _current_ requirements, it can stop you from implementing _new_ requirements! What's more, repetitive copy-paste code is friendly to AI-assisted change.
## Avoid splitting stuff up. Use one big blob!
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/5_peacock.avif" alt="Peacock" />
</figure>
Why does the peacock not ditch that stupid enormous tail? Well, the males can’t, because the females select for it. But the peahen can’t ditch her selection choice either: she'd have sons with small tails, who wouldn’t get selected!
<figure className="not-prose left">
<img
src="https://www.granola.so/blogImages/evolve/5_peacock_sequence_diagram.avif"
alt="Peacock sequence diagram"
/>
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Peacock sequence diagram.</i>
</figcaption>
</figure>
**Protocols inhibit change,** and the peacock has a broken protocol that equates "large tails" with "fitness". An asexual peacock could ditch the tail. But with two sexes, there’s no way to change without global coordination. Nature's lesson for us: **avoid splitting stuff up.** And especially avoid any splits that create distributed systems! It’s easier to change one big thing than to change many small things talking to each other. Your professor is not here to punish you any more. It's okay to keep everything in one file!
<figure className="not-prose right">
<img
src="https://www.granola.so/blogImages/evolve/6_client_api_db.avif"
alt="Client, database, and API"
/>
</figure>
Even the earliest prototypes often look like this: a client, a database, and an API between them. But with this design, you’ve already introduced two splits!
<figure className="not-prose left">
<img
src="https://www.granola.so/blogImages/evolve/7_one_blob.avif"
alt="Initial version of Granola"
/>
</figure>
By contrast, **the first prototype of Granola was an isolated desktop app.** It talks to the things it needs to, but is otherwise a single blob.
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/7_client_db.avif" alt="Granola using Supabase" />
</figure>
We eventually had to have some server-side stuff. Typically this means building an API layer. But we avoided that by using Supabase, which lets clients directly interact with your central database. Instead of two interfaces slowing you down, we just had one.
## Avoid auto-update. Use direct distribution!
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/8_cambrian_species.avif"
alt="Cambrian species"
/>
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Btw, notice all the repeated segments.</i>
</figcaption>
</figure>
Here are some of the bizarre life forms that lived alongside our ancestor _Pikaia_. Life is always exploring many variants in parallel! That’s the only way to quickly explore a giant possibility space. Yet most software distribution is sequential. `v1` then `v2` then `v3`, and so on. Web apps are constrained to a single “production” version being explored by users. Mobile apps are constrained to a single version published on an app store. Bad for exploration.
<figure className="not-prose left">
<img
src="https://www.granola.so/blogImages/evolve/10_dmg.avif"
alt="Direct software distribution via .dmg file"
/>
</figure>
Instead, our app is directly distributed via a .dmg file. This means **we can make some radical code changes, cut a new build, and send it to a single user.** This is great for evolving a product, because we're evaluating many versions in parallel.
(You might be thinking: "But we have feature flags." Good, but you can't make _radical_ changes on a feature flag, because your single production version must act as a superposition of all possible software changes.) In early life, avoid linear auto-update. Instead, use direct distribution.
## Help your software versions die
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/11_opabinia.avif" alt="Opabinia" />
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Copy-pasted eyes.</i>
</figcaption>
</figure>
_Opabinia_ lived alongside our ancestor. He had five eyes on stalks, and a single, central claw. But _Opabinia_'s descendants are not alive today — perhaps because he was a stupid design. Most of the Cambrian forms were evolutionary dead ends.
Without death, natural selection doesn’t work! And yet much conventional advice makes it hard for us to kill our bad software versions.
<figure className="not-prose left">
<img src="https://www.granola.so/blogImages/evolve/12_references.avif"
alt="References to software versions"
/>
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>(From left) Living Granola, dead Granola.</i>
</figcaption>
</figure>
What is a "dead" software version? It's one with no more references to it. Think garbage collection. So, **to let your software die, avoid unnecessary references to it.** Let's look at common references we can avoid.
## Avoid automated tests. Test manually!
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/13_tests.avif" alt="Tests" />
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Hey, come back here!</i>
</figcaption>
</figure>
So you’ve made a software change, but now the tests are broken. Don't feel bad: it's the tests' fault, not yours!
**Tests are chains, stopping your program from running free.** The tests say: "Bad code! Stop changing! Go back and be the previous program!" So avoid writing tests. Just test the things that are unlikely to change. Test everything else manually.
(Note: type-checking is different. It tests correctness properties that apply to _any_ program. A good type-checker lets you move fast without breaking as many things.)
## Avoid unnecessary users. Build for yourself!
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/13_users.avif" alt="Users" />
<figcaption className="text-sm text-gray-500 mt-2 text-center italic">
<i>Please support us!</i>
</figcaption>
</figure>
You've experienced this too: you want to remove something from your product, but some obscure users loudly complain, so you give in. Conventional advice says to launch ASAP. But **people using your software keep it alive, and so they can slow down change.** Instead, avoid all unnecessary users. Build for a small set of target users. (That target might just be yourself!)
## Avoid landing pages. Onboard manually!
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/13_resources.avif" alt="User-facing resources" />
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>We'll remember you forever!</i>
</figcaption>
</figure>
Conventional advice is to focus on top-of-funnel experience. Build a landing page to sell the product. Write docs and build a slick onboarding into the app. But all these user-facing resources reference a specific version of your product! And so they make it harder to kill that version.
**At Granola, we deliberately spent a long time pre-launch.** We targeted a small niche, and manually onboarded everyone. This reduced distractions, made it easier to throw stuff away, and helped us practice for when we eventually did build a landing page and onboarding.
## Best practices for pre-launch software are very different
<figure className="not-prose right">
<img src="https://www.granola.so/blogImages/evolve/14_midwit.avif" alt="Midwit meme" />
<figcaption className="text-sm text-gray-500 mt-2 text-center">
<i>Midwit meme for you to copy-pasta.</i>
</figcaption>
</figure>
Conventional advice says that good code is "clean code" with high test coverage, and that teams prioritize early launches, continuous delivery, and top-of-funnel experience. But in an early startup, your sole focus is to search for a product, and these "best practices" can slow down this search. Try optimizing for change, by using low-abstraction copy-paste, all in one place, with no tests. Distribute your app manually, and onboard people manually. That's what we did. After 12 months, we now think we've found our product, and it might be time to re-evaluate our approach. If you’d like to join our journey, get in touch!

Hi everyone!
This week it looks like we are finally entering the summer/holiday season and the pace of major React announcements is slowing down. We will also be taking a short summer break, skip 2 issues, and be back on July 17.
On the React side, we continue to have interesting content related to the Suspense drama from last week. A new React Router feature permits you to code split your route tree.
On the React Native side, it looks like the team is trying to release v0.75 as RC, and encountering some roadblocks, but it’ll probably be out soon.
The most exciting news to me is the TypeScript 5.5 stable release: it’s a great one, notably for predicate type inference! The State of JS survey results are also out if you want to explore JS trends.

**[The Category-Defining React Grid for Your Enterprise](https://1771technologies.com/graphitegrid)**
Data grids are complex components of web applications, but current solutions are inefficient, require a lot of maintenance, and perform poorly. [Graphite Grid](https://1771technologies.com/graphitegrid) transforms the landscape with two key features: retargetable rendering and reactive signal state.
**Graphite Grid** separates grid state from view logic, allowing a single unified state model to support a variety of render targets, declaratively or imperatively. It includes a **DOM and Canvas** renderer, giving developers flexible, high-performance options 🚀.
Graphite Grid is declarative and consistent, leveraging state signals to ensure seamless integration with your application. Designed with **React in mind**, it is the only JavaScript data grid built with React's state management primitives. [Try it now!](https://1771technologies.com/graphitegrid/demo)

[](https://github.com/remix-run/react-router/blob/main/CHANGELOG.md#v6240)
**📦 [React-Router 6.24 - Lazy Route Discovery](https://github.com/remix-run/react-router/blob/main/CHANGELOG.md#v6240)**
This React Router release includes a new `unstable_patchRoutesOnMiss` hook that will be called when React Router can’t match any existing route. It permits you to load additional routes and implement code splitting for your routes instead of keeping them all in a single monolithic module. A welcome feature for large apps with thousands of routes, that now don’t need to load all of them upfront, delaying hydration.
Remix was supposed to take a nap, but apparently not yet! 📦 [Remix 2.10](https://remix.run/docs/en/main/start/changelog#v2100) is out and already leverages that new React Router feature by exposing it through a convenient [“Fog of War”](https://remix.run/docs/en/main/guides/fog-of-war) feature that you can enable with a simple `future.unstable_fogOfWar` flag. An early discovery optimization has also been implemented to avoid waterfalls.

### Real-Life Applications of AI in RPM
This section explores the power of AI in remote patient monitoring and highlights real-life examples that showcase its immense potential.
### A new era of personalized healthcare
AI in remote patient monitoring has ushered in a new era of personalized healthcare. AI algorithms can create individualized patient care and treatment plans by analyzing vast amounts of patient data, including medical history, vital signs, and lifestyle choices.
#### Real-life Example #1
A patient with diabetes may utilize an AI-powered remote patient monitoring system that tracks their blood glucose levels, physical activity, and dietary habits. Based on the data, the AI algorithm recommends personalized meal plans and exercise routines, leading to better glycemic control and reduced risk of complications.
### Early Detection of Complications
AI in remote patient monitoring enables early detection of primary care health issues, sometimes identifying them before they show noticeable symptoms. In remote patient monitoring, AI algorithms continuously analyze patient data to identify subtle changes in vital signs or symptoms that may indicate potential health risks.
**Real-life Example #2**
A patient with severe heart issues uses an AI-driven remote monitoring device that tracks their heart rate, blood pressure, and respiratory rate in real-time.
The AI algorithm detects irregular patterns in the patient’s vital signs, signaling the possibility of an impending heart failure exacerbation. In this scenario, a qualified healthcare professional receives an alert. The healthcare provider can then adjust the patient’s medication and prevent hospital admission promptly.
### Predictive Analytics for Disease Progression
(Source: [Link](https://www.google.com/url?sa=i&url=https://www.appventurez.com/blog/predictive-analytics-in-healthcare&psig=AOvVaw2QWWnWBKrWVu-mpgJba51l&ust=1719422834357000&source=images&cd=vfe&opi=89978449&ved=0CBQQjRxqFwoTCMiRnKyj94YDFQAAAAAdAAAAABAE))
Vital signs such as temperature, pulse, respiratory rate, and mean arterial pressure are continuous predictors of emergency department visits. AI-powered predictive analytics are crucial in remote patient monitoring by forecasting disease progression and potential complications.
These algorithms analyze historical patient data, current health metrics, and other relevant factors to predict the likelihood of certain health events occurring in the future.
**Real-life Example #5**
A patient with [chronic obstructive pulmonary disease](https://www.mayoclinic.org/diseases-conditions/copd/symptoms-causes/syc-20353679) (COPD) uses an AI-enabled remote pulse oximeter device. The RPM device tracks lung function, oxygen levels, and respiratory symptoms. The AI algorithm analyzes the collected data and identifies patterns indicating a higher exacerbation risk.
The patient’s healthcare team receives an alert, allowing them to adjust medication and provide timely interventions, thereby preventing severe respiratory episodes and hospitalizations.
This illustrates AI’s predictive capabilities in enhancing RPM by identifying potential complications before they escalate. Predictive measures lead to improved patient outcomes and a higher quality of life for individuals managing chronic conditions.
### Patient and Provider Perspectives on AI

### Patients’ Point of View
A [survey by Morning Consult](https://pro.morningconsult.com/analysis/ai-health-care-americans-public-opinion) revealed that about 70% of US adults have concerns about the increased use of AI in healthcare. Baby Boomers showed the most concern at 77%, followed by Gen X at 70% and Millennials and Gen Z at 63%.
Most people prefer important healthcare tasks to be led by medical professionals rather than AI, with 84% preferring a provider to prescribe pain medication, 80% for diagnosing a rash, 71% for reading a scan, and 69% for managing a patient’s diet.
Perceptions differ by medical specialty. Parents are mainly concerned about diagnostic errors and incorrect treatment recommendations in computer-assisted healthcare for children.
However, many parents see benefits such as rapid diagnosis and catching early symptoms that might be missed by humans. The majority of parents are comfortable with AI in scenarios like determining the need for antibiotics, radiograph interpretation, and bloodwork.
Overall, children and youth generally have a positive view of artificial intelligence (AI) in healthcare, showing significant knowledge and a desire to be involved in AI research and deployment. Across demographics and specialties, patients believe AI will improve healthcare in the long term.
### Provider and Medical Student Perspectives
Providers’ perspectives on AI are critical for patient trust and outcomes. If providers do not trust AI tools, patients are unlikely to feel comfortable with them.
Acceptance of AI involves balancing multiple factors, such as the perceived loss of professional autonomy and difficulties integrating AI into clinical workflows. Including end-users in early development stages and providing appropriate training can facilitate AI acceptance.
A [study by Researchgate](https://www.researchgate.net/publication/371782477_Radiology_as_a_Specialty_in_the_Era_of_Artificial_Intelligence_A_Systematic_Review_and_Meta-analysis_on_Medical_Students_Radiology_Trainees_and_Radiologists) shed some light on how professionals feel. Radiologists and medical students are particularly concerned about healthcare AI. Concerns among medical students and interns include the impact of AI on their specialty choice and the need for AI training in medical school curricula.
Recruitment challenges in radiology arise due to AI concerns, with some medical students believing AI could make the specialty obsolete. Researchers argue that misinformation about AI contributes to these challenges and emphasize AI’s potential to support radiologists and advance the field.

Healthcare has three main goals: improving the care experience, enhancing health outcomes, and reducing costs, known as the Triple Aim of Healthcare. Achieving these goals can be challenging for people even if they successfully know [how to build a healthcare app](https://www.raftlabs.com/blog/how-to-develop-a-healthcare-app-like-practo-features-tech-stack-cost/) or have existing healthcare solutions, but AI offers a solution.
AI can help healthcare organizations better use their data, redefining care delivery and making it easier to achieve the triple aim. One key AI tool is remote patient monitoring (RPM), which uses digital technology to monitor patients’ vitals and health data outside traditional healthcare settings.
This tech securely sends health information between patients and providers, leading to better clinical decisions, better telehealth services, earlier interventions, and more preventive care. [Top RPM apps](https://www.raftlabs.com/healthcare/resources/apps/best-remote-patient-monitoring-platforms/) enabled with AI support patient enrollment, engagement, and education, ensuring adherence and reducing administrative work.
### Promoting Clinical Efficiency
AI-enabled RPM gathers data passively, allowing clinicians to focus on diagnosing, educating, and treating patients, thus improving productivity and care efficiency.
Clinicians no longer need to request health status information frequently or wait for the next visit to adjust care plans. Instead, constant health data transmission highlights critical cases, enabling preventive and personalized care.
### Delivering Better Outcomes
RPM shifts healthcare from reactive to value-based preventive care by providing continuous data access. This is crucial for patients with chronic diseases like hypertension, heart failure, diabetes, and obesity.
Studies show RPM significantly lowers blood pressure, reduces heart attack and stroke rates, and improves blood glucose levels and weight reduction. AI-enabled RPM can also increase patient adherence by up to 36%, helping clinicians spot trends and adjust care plans and other telehealth services for better outcomes.
### Reducing Costs
With rising chronic disease rates and healthcare costs, AI-enabled RPM is the future of healthcare delivery. It meets the triple aim by reducing hospitalizations, deaths, and per-patient costs. A [study by ScienceDirect](https://www.sciencedirect.com/science/article/pii/S2444569X2300029X) shows that AI in healthcare can potentially cut down healthcare costs in the US by $150 billion by 2026 by shifting from reactive to proactive health management.
### Achieving the Triple Aim
AI and RPM together enable earlier detection of health issues, quicker interventions, fewer emergency room visits, and reduced hospitalizations. This enhances healthcare provider support, improves patient outcomes, boosts financial performance, and addresses complex healthcare challenges.

I like this joke yet I think it's obsolete.
I remember myself 4 years ago trying to comprehend all the concepts behind reactive programming, learning ways to write my streams and manipulate them using operators. It wasn't easy besides you had to keep up with all new changes (and there're a few of them). But today RxJS is a mature toolchain with a lot of learning materials, the amount of effort the team puts into making the library more accessible for common folks like me is truly impressive.
Yet it's still a common opinion that RxJS is not very friendly for newbies. Besides core concepts of reactive programming (that are not specific to RxJS), the number of operators available for a user might be intimidating.
As I stated above, the maintainers' team did and doing a great job simplifying and improving the API. And luckily we don't need to remember all of them as a tiny portion is actually needed for everyday use.
Still, you can find yourself a bit lost thinking of what operator should I use in certain cases. Don't worry the docs got you covered, it contains a super useful operator decision tree util https://rxjs.dev/operator-decision-tree. Answering simple question about your intentions with the stream it can suggest the most fitting operator for your case.
It's great, but I prefer the table view of the same tree. And unsurprisingly there's such a table https://xgrommx.github.io/rx-book/content/which_operator_do_i_use/index.html, but there's another "but" – it's a bit outdated thus I present you the up-to-date (at the time of writing this post) version of the same table:

Hello, fellow developers! 🌟
In this post, we'll walk through creating your first API in a MERN (MongoDB, Express.js, React, Node.js) project using ES6 modules and modern JavaScript features. This guide is perfect for beginners who want to get started with the basics.
## Prerequisites
Before we start, ensure you have the following installed on your machine:
- Node.js
- npm (Node Package Manager)
- MongoDB (you can use MongoDB Atlas for a cloud-based solution)
- A code editor (VS Code is a popular choice)
## Step 1: Setting Up the Project
First, let's create our project directory and set up a new Node.js project.
```bash
mkdir mern-api
cd mern-api
npm init -y
```
Install the necessary dependencies.
```bash
npm install express mongoose dotenv
```
## Step 2: Creating the Server with Express
Create a file named `server.js` in your project root and add the following code:
```javascript
import express from 'express';
import mongoose from 'mongoose';
import dotenv from 'dotenv';
import userRoute from './routes/user.route.js';
dotenv.config();
mongoose
.connect(process.env.MONGO)
.then(() => {
console.log('mongodb is connected');
})
.catch((err) => {
console.log(err);
});
const app = express();
app.listen(3000, () => {
console.log('express is working!!!');
});
app.use('/api/user', userRoute);
```
## Step 3: Defining a Model
Create a new directory called `models` and inside it, create a file named `User.js`:
```javascript
import mongoose from 'mongoose';
const userSchema = new mongoose.Schema(
{
username: {
type: String,
required: true,
unique: true,
},
email: {
type: String,
required: true,
},
},
{ timestamps: true }
);
const User = mongoose.model('User', userSchema);
export default User;
```
## Step 4: Creating a Controller
Create a new directory called `controllers` and inside it, create a file named `user.controller.js`:
```javascript
export const test = (req, res) => {
res.json({
message: 'Test api is working',
});
};
```
## Step 5: Creating Routes
Create a new directory called `routes` and inside it, create a file named `user.route.js`:
```javascript
import express from 'express';
import { test } from '../controllers/user.controller.js';
const router = express.Router();
router.get('/test', test);
export default router;
```
## Step 6: Integrating Routes in Server
Ensure your `server.js` uses the newly created routes:
```javascript
import express from 'express';
import mongoose from 'mongoose';
import dotenv from 'dotenv';
import userRoute from './routes/user.route.js';
dotenv.config();
mongoose
.connect(process.env.MONGO)
.then(() => {
console.log('mongodb is connected');
})
.catch((err) => {
console.log(err);
});
const app = express();
app.listen(3000, () => {
console.log('express is working!!!');
});
app.use('/api/user', userRoute);
```
## Step 7: Testing Your API
To test your API, you can use tools like Postman or Insomnia.
### GET Test Route
```
GET http://localhost:3000/api/user/test
```
## Congratulations!
You've successfully created your first API in a MERN stack project using modern JavaScript features. This is just the beginning; you can now expand on this by adding more routes, implementing user authentication, and much more.

1,900,633 | Embedding Bokeh into HTML with Pyscript, a CSS resize handle & Custom JS callback passing results back to a div on our html page | Here we explore a deeper dive into Pyscript where all my code below is circa 2024 (the newest version... | 27,896 | 2024-06-28T12:21:47 | https://dev.to/rickdelpo1/embedding-bokeh-into-html-with-pyscript-a-css-resize-handle-custom-js-callback-passing-results-back-to-a-div-on-our-html-page-4f3o | python, javascript, webdev, tutorial | Here we explore a deeper dive into Pyscript where all my code below is circa 2024 (the newest version of Pyscript).
Pyscript allows us to embed a Bokeh Chart into HTML. Then we make our html interactive by adding some CSS with a resize handle. We also make our bokeh interactive using the stretch_both method which allows us to entirely fill the html div we are embedding into. When we drag the resize handle either up, down or sideways, our bokeh chart responds accordingly and also renders the plot width and height coordinates using a JS callback with custom JS.
In the old days, prior to 2022 when Pyscript was invented, in order to embed bokeh into html we needed bokeh on a server along with lots of python and javascript to make this solution work. Now Pyscript shortens the process with the embed.embed_item method and ffi (foreign function interface, circa pyscript 2024) which converts a Python object into its JavaScript counterpart, thus enabling web interactivity.
**Embedding vs showing**
In Pyscript we are embedding and in Python we are showing. Both involve an html file but it is the Pyscript html file we want to write our code in and share with others.
More specifically when working with Bokeh directly in Python there is the show() method and in Pyscript we have the embed.embed_item() method and these are separate ways to render Bokeh.
Our show() method creates an output html file and opens bokeh in a browser. This bare html template is not what we want because it is not usable code, it is mainly a combo of json and javascript just to render a page. The link to this html page is not the link we want to provide others either. Show() actually creates an html file after running from Python but we want to be in the html before running so we can manage our code. When writing Pyscript we start with html and script tags in a notepad and then save as html on our local drive before we click the link to run it. We will use this link to share with others.
**Interactivity Everywhere**
In this example the idea of interactivity encompasses more than just bokeh interactivity, it also combines it with html/css interactivity and javascript interactivity (ffi), plus optional custom js if needed. HTML, CSS, Bokeh and Javascript all play nicely together which is why I chose Bokeh in the first place. Bokeh offers a stretch_both method which allows the bokeh chart to completely fill the html object which is a div in this case. Then we apply pure css to resize the div and as div is wider so is bokeh. Our custom js works here too, so lots of interaction happening in our example below.
**Pyscript link, not the show() link**
In this use case we can save the Pyscript link to a remote html web server so as to provide a public link to others. When the user clicks the link he can also press ctrl u to view its source.
Here is my public link
https://rickd.s3.us-east-2.amazonaws.com/Pyscript+Template+with+div+resize+handle_2.html
With this pyscript link we can copy and edit the code in a notepad and then resave to your local link or upload to a public domain.
**Custom JS in a Callback**
Custom Javascript is optional and adds more interactivity to our app. This custom JS component allows us to pass Python args into the javascript and then out to an html div. We can trigger an event to call the callback which executes the custom js. Python allows us to build bokeh in Pyscript and Javascript allows us to build interactivity in our callback where we respond to the python event. Here in our example, the event is where we drag the resizing handle which triggers some custom js to display a result in an html div. Pyscript provides a healthy environment where Python, Javascript and HTML can play and interact together in harmony.
**My code - Pyscript, Python, CSS all on one sharable HTML page**
The purpose of this example is to show how an elongated grid distorts trend lines and angles. The chart grid lines need to be equalized or squared in order to give us an aspect ratio of 1:1 between height and width of the grid lines for the trends on a line chart to be accurate. For example, a stock chart has normally elongated grid lines thus flattening the angle of any slopes. This is why angles should never be applied to stock prices unless the height and width of grid lines are equal.
Note: in a previous version of bokeh the resizing method was abandoned so we need to do resizing on the html side now which is why I provide this example.
So here it is
```js
<!DOCTYPE html>

<html lang="en">

Today, I want to share... | 27,620 | 2024-06-28T12:21:32 | https://www.superviz.com/design-pattern-4-publisher-subscriber-pattern-for-frontend-developers | javascript, architecture, learning, webdev | In the previously article of this series I covered about the [Observer Pattern](https://dev.to/superviz/design-pattern-3-observer-pattern-36eo). Today, I want to share with you the Publisher and Subscriber pattern, or the PubSub for the closest friends. I highly recommend reading and understanding the Observer Pattern before continuing this quest.
## Pub Sub Pattern Design
The PubSub Pattern is a messaging pattern that promotes loose coupling and scalability. This pattern revolves around dispatching messages from publishers to an unspecified number of subscribers or listeners, thereby promoting a many-to-many dependency between objects.
### Real case scenario
Let’s consider a chat group application. The Pub/Sub system can handle the sending and receiving of messages efficiently:
#### Subscribing to a event
When a chat window is opened, it subscribes to an event, such as `newMessage`.
This is done using `pubsub.subscribe("newMessage", callback)`. The callback function is what will be executed when a new message is published to the `newMessage` event. In this case, the callback logs the new message and updates the chat UI.
```jsx
pubsub.subscribe("newMessage", function(data) {
console.log("New message received:", data);
// Here you would update the chat UI with the new message
});
```
#### Publishing to a event
When a user sends a message, it is published to the newMessage event using pubsub.publish("newMessage", messageData). All chat windows subscribed to the newMessage topic will have their callback functions executed with the new message as the argument.
When a user sends a message, it's published to the `newMessage` event using `pubsub.publish("newMessage", messageData)`. All chat windows subscribed to the `newMessage` topic will have their callback functions executed with the new message as the argument.
```jsx
const messageData = { user: "User A", text: "This is what the user had typed" };
pubsub.publish("newMessage", messageData);
```
In this way, the Pub/Sub system allows for the decoupling of chat windows (subscribers) and message senders (publishers). The chat windows don't need to know about who sends messages (like we saw on the previously post about the observer pattern), they just need to know what to do when a message is received.
Similarly, message senders don’t need to know who will receive the messages; they just need to send messages to the right topic.
### How to build a pub sub
To construct a PubSub system, we need to maintain a record of events or 'topics' and their respective subscribers. This can be done with a simple JavaScript object. When a new message is published, we look up the associated subscribers and execute their callback functions. This allows for a dynamic and flexible system where publishers and subscribers can be added or removed at runtime.
```jsx
class PubSub {
static events = {}; // It has the an empty list of events
// The subscribe method takes an event name and a callback function
subscribe(eventName, callback) {
if (!this.events[eventName]) {
// If the event doesn't exist yet, initialize it as an empty array
this.events[eventName] = [];
}
// Push the callback function into the array of callbacks for the given event
this.events[eventName].push(callback);
}
// The publish method takes an event name and data
publish(event, data) {
// If the event doesn't exist, or there's no subscribers for this event, return
if (!this.events[event]) {
return;
}
// For each subscriber of this event, call the callback function with the provided data
this.events[event].forEach((callback) => {
callback(data);
});
}
}
```
Let me break down this code a bit:
The `PubSub` class has a static `events` property, which is an object that will store all the events (or topics) and their corresponding subscribers (callback functions).
The `subscribe` method is used to register a new subscriber for a given event. It takes an event name and a callback function as arguments. If the event does not exist yet, it initializes it as an empty array in the `events` object. Then, it adds the callback function into the array of callbacks for the given event.
The `publish` method is used to publish new data to an event. It takes an event name and the data to be published as arguments. If the event does not exist or there are no subscribers for this event, it simply returns and does nothing. If there are subscribers, it calls each subscriber's callback function, passing the published data as an argument.
In the context of a chat application, the `subscribe` method would be used to register a new chat window that should receive new messages, and the `publish` method would be used to send a new message to all chat windows that have subscribed to receive new messages.
You can read more about how to use the publish and subscribe method across devices with the article: [**Understanding and implementing Event-Driven Communication in Front-End Development**](https://dev.to/superviz/understanding-and-implementing-event-driven-communication-in-front-end-development-e75).
## Real-time Data Engine
This is an important part of the architectural of a software development, and yet, in the majority of cases, not the business core of what you are building. Creating a reliable and scalable PubSub system that syncs data between different instances of our application can be challenging.
We are in 2024, meaning that there is already a solution to it: the [Real-time Data Engine](https://docs.superviz.com/react-sdk/presence/real-time-data-engine) tools, specifically the [SuperViz SDK](http://superviz.com/). It offers a real-time collaboration and communication SDK and API, designed for developers building real-time web applications.
Using SuperViz you can create a room with several participants that when publishing an event it will be broadcasted to all the participants in the room that are accessing it through different devices and networks. This means that any updates made by one participant will be reflected in real time across all devices, providing a seamless and collaborative experience.
[SuperViz](http://superviz.com/) provides the infrastructure necessary to build real-time, collaborative applications. This includes the ability to also catch this events on your backend using webhooks, and as well to publish an event with a simple HTTP Request, to name a few features.
Please let me know in the comments what other design patterns you would like to learn about, and don’t forget to share your knowledge! | vtnorton |

Estava implementando aqui um formulário com validação Yup e me deparei com dois campos que nunca tinha trabalhado: `select` e `input file`.
Procurei algumas formas de fazer a melhor validação desses campos e confesso que achei bem escasso essas informações. Então vou deixar registrado aqui caso alguém queira uma fonte de ajuda na hora de implementar esses campos.
Bom, o formulário que implementei é esse:
E a solução que implementei foi essa:
___
### O que eu usei
- O [Yup.mixed()](https://github.com/jquense/yup?tab=readme-ov-file#mixed) trata todos os tipos, mas você também consegue tipar para receber algo específico.
- O [Yup.oneOf()](https://github.com/jquense/yup?tab=readme-ov-file#schemaoneofarrayofvalues-arrayany-message-string--function-schema-alias-equals) me ajudou a setar corretamente as `options` do meu `select` e a validar se o campo estava preenchido, se não tivesse preenchido ele retornava uma mensagem de erro personalizada.
- O [Yup.test()](https://github.com/jquense/yup?tab=readme-ov-file#schematestname-string-message-string--function--any-test-function-schema) eu adicionei para validar o `input file`. Nele eu precisava verificar se o campo estava preenchido e se era um `.pdf`, e também tem o retorno de mensagens de erro personalizadas.
Essa foi uma solução que eu desenvolvi para o que era necessário.
**Sugestão**: Se você tem alguma sugestão de melhoria ou qualquer que seja, comenta aí.
**Ressalva**: Também deve haver validação no backend para prevenir alteração no tipo do arquivo via proxy.

1,904,059 | React vs. Svelte: A Quick Comparison of Frontend Technologies | As a web developer, choosing the right frontend framework can significantly impact the efficiency,... | 0 | 2024-06-28T12:19:21 | https://dev.to/monyasau/react-vs-svelte-a-quick-comparison-of-frontend-technologies-3l5p | webdev, beginners, react, svelte | As a web developer, choosing the right frontend framework can significantly impact the efficiency, speed and performance of your projects. While React is pretty popular, Svelte is a close alternative. In this article, I’ll compare Svelte and React, and highlight their key differences and benefits
[Svelte](https://svelte.dev/), Which is made by Rich Harris, is a new frontend framework that shifts much of the work to compile time which results in highly optimized vanillaJS at runtime, eliminating the need for a virtual DOM unlike React and reducing the bundle size at the end.
[React](https://react.dev/), developed by Facebook, is a popular library for building user interfaces, and applications. It uses a virtual DOM to efficiently update the UI in response to state changes.
**Key Differences between Svelte and React**:
- **Virtual DOM Usage**: React uses virtual DOM for updating changes in the app while Svelte does not use virtual DOM
- **JSX Syntax**: React uses JSX which is a combination of JavaScript and XML/HTML while Svelte doesn't use JSX
**Comparisons of Svelte & React**:
1, **Performance**:
- **Svelte**: Directly updating the DOM lead to faster runtime performance and smaller bundle sizes.
- **React**: Virtual DOM provides efficient UI updates but also results in larger bundle sizes.
2, **Learning Curve**:
- **Svelte**: Easier to learn with straightforward reactive assignments and simple state management.
- **React**: harder learning curve due to JSX and the virtual DOM concept.
3, **Use Cases**:
- **Svelte**: when making high-performance applications where bundle size and runtime speed are critical.
- **React**: when making complex applications with extensive state management needs and a robust component structure.
**Who wins**? : It depends on your project! React for experience and support due to large community, or choose Svelte for speed and ease of use.
**My Expectations for HNG Internship with React**

1,904,057 | Paddler - open-source llama.cpp load balancer (self-host LLMs in production) | Paddler is an open-source load balancer and reverse proxy designed to optimize servers running... | 0 | 2024-06-28T12:16:20 | https://dev.to/mcharytoniuk/paddler-open-source-production-ready-llamacpp-load-balancer-ecf | opensource, devops, ai | Paddler is an open-source load balancer and reverse proxy designed to optimize servers running [llama.cpp](https://github.com/ggerganov/llama.cpp).
Typical strategies like round robin or least connections are not effective for [llama.cpp](https://github.com/ggerganov/llama.cpp) servers, which need slots for continuous batching and concurrent requests.
Paddler overcomes this by maintaining a stateful load balancer that is aware of each server's available slots, ensuring efficient request distribution. Additionally, Paddler uses agents to monitor the health of individual [llama.cpp](https://github.com/ggerganov/llama.cpp) instances, providing feedback to the load balancer for optimal performance. Paddler also supports the dynamic addition or removal of [llama.cpp](https://github.com/ggerganov/llama.cpp) servers, enabling integration with autoscaling tools.
## Feature Highlight
### Aggregated Health Status
Paddler overrides `/health` endpoint of `llama.cpp` and reports the total number of available and processing slots.
### Buffered Requests (Scaling from Zero Hosts)
Load balancer's buffered requests allow your infrastructure to scale from zero hosts by providing an additional metric (requests waiting to be handled).
It also gives your infrastructure some additional time to add additional hosts. For example, if your autoscaler is setting up an additional server, putting an incoming request on hold for 60 seconds might give it a chance to be handled even though there might be no available llama.cpp instances at the moment of issuing it.
Scaling from zero hosts is especially suitable for low-traffic projects because it allows you to cut costs on your infrastructure—you won't be paying your cloud provider anything if you are not using your service at the moment.
### State Dashboard
Although Paddler integrates with the StatsD protocol, you can preview the cluster's state using a built-in dashboard.
## Final Thoughts
The project is gaining some traction. Let me know if you also use it in prod, and I will highlight your project in the repo. Thank you all for giving me feedback on it so far. I always appreciate it. :)

1,904,055 | What is namespace in PHP and it's use? | What is a Namespace? A namespace is a way to group related classes, functions, and... | 0 | 2024-06-28T12:14:06 | https://dev.to/ghulam_mujtaba_247/what-is-namespace-in-php-and-its-use-a1h | webdev, beginners, programming, php | ## What is a Namespace?
A namespace is a way to group related classes, functions, and constants together, avoiding conflicts with other code.
## Defining a Namespace
A namespace is defined using the `namespace` keyword followed by the namespace name.
```php
namespace Core;
```
## Using the `use` Keyword
The `use` keyword is used to import classes, functions, and constants from other namespaces into the current namespace.
```php
use PDO;
```
This imports the `PDO` class from the global namespace into the current namespace (`Core`).
```php
namespace Core;
use PDO;
class Database {
public $connection;
public $statement;
public function __construct($config, $username = 'root', $password = '') {
$dsn = 'mysql:' . http_build_query($config, '', ';');
$this->connection = new PDO($dsn, $username, $password, [
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC
]);
}
}
```
## Without the `use` Keyword
Without the `use` keyword, you would have to use the fully qualified name of the `PDO` class, like this `\PDO`:
```php
namespace Core;
class Database {
public $connection;
public $statement;
public function __construct($config, $username = 'root', $password = '') {
$dsn = 'mysql:' . http_build_query($config, '', ';');
$this->connection = new \PDO($dsn, $username, $password, [
\PDO::ATTR_DEFAULT_FETCH_MODE => \PDO::FETCH_ASSOC
]);
}
}
```
## Importing Namespaces
Namespaces can be imported using the `use` keyword, like this:
```php
use Core\Database;
```
This imports the `Database` class from the `Core` namespace into the current namespace.
## When to Use Namespaces
Namespaces are useful when:
- You want to avoid conflicts with other code.
- You want to organize your code into logical groups.
- You want to use classes, functions, and constants from other namespaces.
```php
use Core\Database;
$db = new Database($config['database']);
```
## Autoloading Classes and Functions
You can automatically load classes and functions using the `spl_autoload_register` function. But first, you need to change the autoloader statement of last project `spl_autoload_register(function ($class) { require base_path("Core/{$class}.php"); });`
to this:
```php
spl_autoload_register(function ($class) {
$class = str_replace('\\', DIRECTORY_SEPARATOR, $class);
require base_path("{$class}.php");
});
```
The statement `str_replace('\\', DIRECTORY_SEPARATOR, $class);` tells that:
- `str_replace` is a PHP function that replaces a string with another string.
- The first argument `('\\',` is the string to be replaced, which is the namespace separator (`\`).
- The second argument `DIRECTORY_SEPARATOR` is the string that will replace the namespace separator. `DIRECTORY_SEPARATOR` is a PHP constant that represents the directory separator (either `/` or `\`, depending on the operating system).
- The third argument `$class` is the string that contains the class name, which may include namespace separators (`\`).
I hope that you have clearly understood it.

1,904,052 | Understanding a Common Backend Golang Problem: Pointers | When developing backend applications in Golang, one common problem that alot of developers often face... | 0 | 2024-06-28T12:10:11 | https://dev.to/oluwayanfunmi_jeje_b7d7fe/understanding-a-common-backend-golang-problem-pointers-1557 | When developing backend applications in Golang, one common problem that alot of developers often face involves the use of pointers. While pointers can be incredibly powerful, they can also introduce complexities and bugs if not handled correctly. In this short article, we'll explore a typical pointer-related issue in Golang and how to address it.
The Problem: Nil Pointer Dereference
A common issue in Golang that almost drove me crazy when i first started learning is the "nil pointer dereference" error. This occurs when a program attempts to read or write to a memory location through a nil (uninitialized) pointer. This can lead to runtime crashes, which are particularly problematic in backend services where stability critical.
Example
Imagine you have a struct representing a user in your backend service:
```go
type User struct {
Name string
Email string
Age int
}
```
You might have a function that initializes a user and performs some operations on it:
```go
func updateUser(user *User) {
user.Name = "Kendrick lamar"
user.Age = 30
fmt.Println("User updated:", user)
}
```
If you call this function with a nil pointer, it will cause a runtime panic:
```go
func main() {
var user *User
updateUser(user)
}
```
Solution: Proper Pointer Initialization
To avoid nil pointer dereference, ensure that pointers are properly initialized before dereferencing them. You can initialize the User struct either directly or using the new keyword:
```go
func main() {
user := &User{}
updateUser(user)
}
```
or
```go
func main() {
user := new(User)
updateUser(user)
}
```
Both of these approaches ensure that the user pointer is not nil, thus preventing the nil pointer dereference error.
Conclusion
Pointers are a powerful feature in Golang, but they require careful handling to avoid common pitfalls like nil pointer dereference. By ensuring proper initialization and checking for nil values, you can write more robust and error-free backend code. Remember, the stability of your backend services often depends on these small but crucial details. I'm hoping to learn more about golang during my [HNG internship](https://hng.tech/internship), been having trouble upskilling and i know that this program will help me.

We'll leverage Terraform to automate the entire process.
## Architecture Overview
Before we get started, let's take a quick look at the architecture we'll be working with:
## Step 1: Create an S3 Bucket
First, we need to create an S3 bucket where we will enable event notifications. Here is the Terraform code to create an S3 bucket:
```hcl
####################################################
# S3 static website bucket
####################################################
resource "aws_s3_bucket" "my-bucket" {
bucket = var.bucket_name
}
```
## Step 2: Create an SNS Topic with Email Subscription
Next, we'll create an SNS topic and set up an email subscription to receive notifications. Below is the Terraform configuration for creating the SNS topic and the email subscription. Policy allows S3 to Publish events to SNS.
```hcl
####################################################
# Create an SNS topic with a email subscription
####################################################
resource "aws_sns_topic" "s3-event-notification-topic" {
name = "s3-event-notification-topic"
policy = <<POLICY
{
"Version":"2012-10-17",
"Statement":[{
"Effect": "Allow",
"Principal": { "Service": "s3.amazonaws.com" },
"Action": "SNS:Publish",
"Resource": "arn:aws:sns:us-east-1:197317184204:s3-event-notification-topic",
"Condition":{
"StringEquals":{"aws:SourceAccount":"197317184204"},
"ArnLike":{"aws:SourceArn":"${aws_s3_bucket.my-bucket.arn}"}
}
}]
}
POLICY
}
resource "aws_sns_topic_subscription" "topic-email-subscription" {
count = length(var.email_address)
topic_arn = aws_sns_topic.s3-event-notification-topic.arn
protocol = "email"
endpoint = var.email_address[count.index]
}
```
## Step 3: Create S3 Event Notifications
Finally, we configure the S3 bucket to send event notifications to the SNS topic. The following Terraform code snippet demonstrates how to set up S3 event notifications:
```hcl
####################################################
# Creating Bucket Event Notification
####################################################
resource "aws_s3_bucket_notification" "bucket-notification" {
bucket = aws_s3_bucket.my-bucket.id
topic {
topic_arn = aws_sns_topic.s3-event-notification-topic.arn
events = ["s3:ObjectCreated:*"] # You can specify the events you are interested in
}
}
```
## Steps to Run Terraform
Follow these steps to execute the Terraform configuration:
```hcl
terraform init
terraform plan
terraform apply -auto-approve
```
Upon successful completion, Terraform will provide relevant outputs.
```terraform
Apply complete! Resources: 4 added, 0 changed, 0 destroyed.
```
## Testing
S3 Bucket with Event Notifications enabled
SNS Topic with email subscription (Confirm the subscription on email before performing any S3 activity)
File upload to create S3 event
Event notifications received via email
## Cleanup
Remember to stop AWS components to avoid large bills.
```terraform
terraform destroy -auto-approve
```
## Conclusion
We have successfully configured AWS S3 event notifications to send emails using an SNS subscription. This setup can be particularly useful for monitoring and alerting purposes.

1,904,043 | "From Logs to Metrics: My Journey in Building a Robust Monitoring System" | As I begin my journey with the HNG Internship Backend Track, I would love to share a personal... | 0 | 2024-06-28T12:00:58 | https://dev.to/ogedi001/from-logs-to-metrics-my-journey-in-building-a-robust-monitoring-system-4p6e | As I begin my journey with the HNG Internship Backend Track, I would love to share a personal experience that truly tested my problem-solving skills as a backend engineer. In this article, I’ll take you through how I tackled a challenging issue and the valuable lessons I learned along the way.
In this project, I was tasked to develop a centralized logging system for collecting logs from different applications using the Elastic Stack. This system is part of a thorough application monitoring solution that includes logs and metrics collection and visualization on Grafana. The system also incorporates Prometheus for metrics scraping and Loki and Promtail for metrics log aggregation.
One of the critical challenges was that these technologies were relatively new to me, and I did not have a deep understanding of them when the task was assigned. Compounding this issue and the fact that my team was not fluent in English, made effective communication difficult. Also, I had limited experience with Linux environments and configuring various service 'yml' files. Connecting Kibana to Elasticsearch for visualization, building custom metrics to meet specific application requirements, and meeting tight deadlines were other significant blockers I faced.
To find my way around these challenges, I resolved to use the following steps:
1. Understanding Key Concepts:
I began by thoroughly studying key concepts such as Elasticsearch, Kibana, Prometheus, and Loki. This involved reading official documentation and watching YouTube videos. Understanding the basics of logs and metrics, as well as what constitutes a centralized logging system, was crucial for laying a strong foundation.
2. Learning Linux Basics:
I spent time learning essential Linux commands and concepts, including installing software, managing permissions and ownership, using nano commands, and configuring services. I practiced these skills using the Windows Subsystem for Linux (WSL), which I had installed before being assigned the task.
3. Splitting the Task Solution:
To manage the complexity, I divided the task into two main components: metrics and a centralized logging service. This helped me focus on each aspect individually and ensure thorough implementation.
4. Installing and Services Configuration:
I started by installing and configuring the services needed to build a centralized logging system using the Elastic Stack. After setting up Elasticsearch, Logstash, and Kibana, I focused on configuring Prometheus, Loki, and Promtail for metrics and metrics log aggregation.
5. Building the Logging Service API:
After configuring and connecting Kibana to Elasticsearch and ensuring all services were running locally, I incorporated the Elasticsearch client API into a Node.js and TypeScript project. I built an endpoint that collects and stores logs in Elasticsearch. The API logic was straightforward: it checks if the index exists, creates a new log document if it does, or creates the index and then the log document if it doesn't.
6. Building Custom Metrics:
I added custom metrics to an existing project, including metrics like total HTTP requests, response time, system uptime and downtime, system availability, and Disk and CPU usage. This application exposes these metrics and I ensure Prometheus can scrape them by connecting the application server address to Prometheus through the Prometheus "yml" configuration file, ensuring that Prometheus can scrape the application's metrics endpoint and visualize these metrics effectively.
7. Configuring Loggers :
I configured the Winston logger to send logs directly to Loki. The logger was used as a method in my application
8. Creating Grafana Dashboard:
I installed Grafana locally, connected multiple data sources, and built custom dashboards for monitoring logs and metrics for my application.
9. Documentation:
Once the system was up and running and had been properly tested, I documented the entire setup process, including configurations and troubleshooting steps. I also created a training guide for my team to help them understand and maintain the system.
Throughout the process, I encountered several challenges, including:
- Configuration And Integration Issues: Configuring in a system with limited memory was challenging and ensured seamless integration between different components of the Elastic Stack.
- Team Communication: Overcoming language barriers within the team to ensure effective explanation and collaboration.
The implementation of the centralized logging and monitoring system resulted in:
- Improved Visibility: Enhanced visibility into application performance and health through comprehensive logs and metrics.
- Operational Efficiency: Streamlined operations and quicker response times to incidents due to real-time monitoring and alerting.
This experience taught me valuable lessons, including:
Importance of Documentation: Keeping thorough documentation is crucial for troubleshooting and onboarding new team members.
Continuous Learning: Adapting to new technologies requires a positive mindset and a proactive approach to learning and problem-solving.
Collaboration: Effective communication and collaboration are vital, especially in diverse teams.
Solving this backend challenge not only benefited our project but also fueled my passion for tackling complex technical problems. I am excited about the opportunity to contribute my skills and learn from industry experts through the HNG Internship. I look forward to the new challenges and opportunities that lie ahead in this internship.

## Como assim interceptar?
Bom caso você não saiba exatamente do que estou falando nós vamos "participar" ou melhor dizendo executar uma função entre o momento que a ação de ler ou atribuir valores é feita até a sua conclusão e para isso iremos ultilizar o objeto [Proxy](https://developer.mozilla.org/pt-BR/docs/Web/JavaScript/Reference/Global_Objects/Proxy).
> É importante dizer que não vou passar método a método do objeto. A ideia é conhecer ele e ir explorando conforme a necessidade.
## Na prática
Vamos ao que interessa, executar o código e ver na prática tudo funcionando, abaixo vou colocar um trecho de código com o proxy interceptando as ações dos objetos e algumas explicações
```javascript
const pessoa = {
nome: 'Cristian',
saldo: 0,
idade: 25
};
const objetoComProxy = new Proxy(pessoa, {
set: (target, propertyKey, newValue) => {
console.log('set', { target, propertyKey, newValue })
target[propertyKey] = newValue;
},
get: (object, prop) => {
console.log('get', { object, prop })
return object[prop]
},
});
pessoa.saldo = 100 // nada acontece, nenhum log é mostrado
// primeiro o get será logado para buscar o valor da propriedade e em seguida o set
// pois estamos usando o objeto com proxy
objetoComProxy.saldo += 100;
/**
* LOG:
* get { object: { nome: 'Cristian', saldo: 100, idade: 25 }, prop: 'saldo' }
set {
target: { nome: 'Cristian', saldo: 100, idade: 25 },
propertyKey: 'saldo',
newValue: 200
}
*/
console.log(objetoComProxy.nome); // get { object: { nome: 'Cristian', saldo: 200, idade: 25 }, prop: 'nome' } e depois Cristian
```
É importante notar que apesar do objeto original ter sido alterado também as funções do Proxy não são executadas, apenas no objeto "proxyado".
## Conclusão
Apesar de um texto bem simples a ideia de hoje foi poder conhecer sobre o Proxy e também aumentar a nossa caixa de ferramentas do JavaScript. Fique a vontade para deixar dúvidas e sugestões.

1,904,032 | A TECHNICAL ARTICLE ABOUT FRONTEND TECHNOLOGIES | Comparing Svelte and SolidJs: Frontend Technologies In the ever-evolving landscape of... | 0 | 2024-06-28T11:48:14 | https://dev.to/ake_michealjnr_31cb330ad/a-technical-article-about-frontend-technologies-3hgp | beginners |
## Comparing Svelte and SolidJs:
Frontend Technologies In the ever-evolving landscape of frontend development, new technologies frequently emerge, each promising to enhance developer productivity and improve user experience. Among these, Svelte and SolidJS have garnered attention for their unique approaches to building web applications. This article delves into the differences between Svelte and SolidJS, highlighting what makes each of them stand out.
## Svelte: A Compiler for Optimized Performance
Svelte is a relatively new frontend framework that takes a different approach compared to traditional frameworks like React or Vue. Instead of doing most of its work in the browser, Svelte shifts that work to the build step. This means that Svelte applications do not include a framework runtime, resulting in smaller and faster applications.
## Key Features of Svelte:
1. No Virtual DOM:
Svelte compiles components into highly efficient imperative code that directly manipulates the DOM, eliminating the need for a virtual DOM.
2. Reactive Assignments:
Svelte uses a unique reactivity model where assignments to variables trigger updates, making state management straightforward and intuitive.
3. Built-in Transitions and Animations:
Svelte provides built-in support for transitions and animations, allowing developers to create rich, interactive user interfaces with minimal effort.
## Advantages of Svelte:
1. Performance:
By compiling to vanilla JavaScript, Svelte applications are often faster and more efficient than those built with frameworks that rely on a virtual DOM.
2. Simplicity:
Svelte's syntax and reactivity model are easy to learn and use, reducing the cognitive load on developers.
## SolidJS: Fine-Grained Reactivity
SolidJS is another innovative frontend framework that emphasizes fine-grained reactivity. Unlike Svelte, SolidJS maintains a reactive system that updates the DOM with minimal overhead, but it does so without a virtual DOM.
## Key Features of SolidJS:
Fine-Grained Reactivity: SolidJS tracks dependencies at a very granular level, ensuring that only the necessary parts of the DOM are updated when state changes. JSX Syntax: SolidJS uses JSX, making it familiar to developers who have experience with React. High Performance: By avoiding the virtual DOM and using fine-grained reactivity, SolidJS achieves high performance and efficient updates.
## Advantages of SolidJS:
1. Efficiency:
The fine-grained reactivity model ensures that updates are highly efficient, leading to better performance.
2. Familiarity:
For developers coming from a React background, the use of JSX and similar concepts makes the transition to SolidJS smoother.
## ReactJS in HNG: Expectations and Feelings
In the HNG internship program, we use ReactJS, a widely adopted frontend library known for its component-based architecture and virtual DOM. ReactJS has a large ecosystem and community support, making it a reliable choice for building scalable web applications.
## What to Expect:
1. Component-Based Architecture:
ReactJS encourages the creation of reusable components, promoting code reusability and maintainability.
2. Virtual DOM:
React's virtual DOM diffing algorithm optimizes updates, ensuring efficient rendering.
3. Rich Ecosystem:
With a vast array of libraries and tools, ReactJS provides solutions for state management, routing, and more.
## Personal Feelings:
I am excited to work with ReactJS in the HNG program. Its robust ecosystem and community support provide a solid foundation for building complex applications. The component-based architecture aligns well with modern development practices, and I look forward to leveraging React's capabilities to create dynamic and responsive user interfaces.

Por lo tanto, es muy importante crear un mapa de edificios y carreteras de buena calidad para facilitar la intervención de los servicios de emergencias.
## El problema del mapeado manual
El mapeado manual de edificios en África es lento y a menudo ineficiente. Las imágenes por satélite suelen ser de baja calidad, la resolución, la iluminación o la distorsión complican mucho el mapeado. Identificar todos los edificios en estas condiciones es un desafío significativo para los equipos humanitarios.
El uso de modelos de reconocimiento de imagen permitirían automatizar el proceso de identificación de edificios en imágenes satelitales, lo que aceleraría significativamente el mapeo y proporcionaría datos más precisos.
## Humanitarian OpenStreetMap Team (HOT)
HOT es una organización sin fines de lucro que utiliza OpenStreetMap (OSM) para apoyar la respuesta humanitaria en todo el mundo. Su enfoque en África es crucial para proporcionar datos geo espaciales precisos y actualizados. Sin embargo, el mapeo manual no siempre es suficiente para cubrir grandes áreas o responder a tiempo a las emergencias.

Cómo podéis ver el modelo funciona impresionantemente bien, en el próximo post explicaré en detalle los pasos que he seguido para conseguir estos resultados. | dservian |
1,904,031 | Was ist der ERC-404 Token-Standard? | Was ist der ERC-404 Token-Standard? Der ERC-404 ist ein neu entwickelter Token-Standard, der von den... | 0 | 2024-06-28T11:44:24 | https://dev.to/thecodedoctor/was-ist-der-erc-404-token-standard-5437 | erc404, solidity, web3js, smartcontract | **Was ist der ERC-404 Token-Standard?**
Der ERC-404 ist ein neu entwickelter Token-Standard, der von den Entwicklern ctrl und Acme von Pandora Labs erfunden wurde. Einfach ausgedrückt, handelt es sich um eine Kombination aus ERC-20 und ERC-721 Token.
**Welches Problem löst ERC-404?**
Das Hauptziel von ERC-404 besteht darin, NFTs (Non-Fungible Tokens) liquide zu machen, sodass sie gehandelt und als Sicherheiten oder Liquidität für DeFi-Protokolle genutzt werden können. Darüber hinaus wird ein Konzept der fraktionierten Eigentümerschaft eingeführt, bei dem mehrere Benutzer einen Teil eines NFTs besitzen können. Dies ermöglicht es einer größeren Anzahl von Benutzern, zuvor unzugängliche Token zu erwerben.
**Technische Eigenschaften von ERC-404**
- **Fraktionierte Eigentümerschaft:** Wie bei ERC-20 Token können ERC-404 Token in Bruchteile unterteilt werden, was es mehreren Benutzern ermöglicht, einen Anteil an einem einzigen NFT zu besitzen.
- **Einzigartigkeit:** Wie bei ERC-721 Token bleibt jeder ERC-404 Token einzigartig und repräsentiert ein individuelles digitales Gut.
- **Liquidität:** ERC-404 Token können einfacher gekauft, verkauft und gehandelt werden, was die Liquidität von NFTs erhöht und sie für Investoren und DeFi-Enthusiasten zugänglicher macht.
**Zusammenfassung**
Der ERC-404 Token-Standard kombiniert die Vorteile von ERC-20 und ERC-721 Token, indem er sowohl die Teilbarkeit von ERC-20 als auch die Einzigartigkeit von ERC-721 bietet. Dies erleichtert den Handel und die Nutzung von NFTs in DeFi-Protokollen und ermöglicht fraktionierte Eigentümerschaft, wodurch NFTs für eine größere Anzahl von Benutzern zugänglich werden.
**Technischer Überblick**
Es ist ganz einfach und kann leicht mit einem Diagramm erklärt werden:
**Funktionsweise des ERC-404 Tokens**
Beim Transfer eines ERC-404 Tokens überprüft der Kontrakt, ob die Anzahl der Tokens, die der Benutzer besitzt, ganzzahlig oder mit Dezimalstellen ist.
**Einfach erklärt:**
**Ganzzahlig:** Wenn ein Benutzer eine ganze Zahl (1, 2, 3, usw.) besitzt, erhält er ein vollständiges NFT.
**Mit Dezimalstellen:** Wenn ein Benutzer eine Dezimalzahl besitzt, erhält er einen Bruchteil des ERC-721 Tokens in fungiblen Tokens.
**Beispiel**
Nehmen wir an, ein Benutzer möchte **69.420 ERC-404** Tokens erhalten:
Der Benutzer erhält **69 ERC721 Tokens** (ganze NFTs).
Der Benutzer erhält **42 ERC20 Tokens** (fungible Tokens), die den Dezimalanteil repräsentieren.
**Technische Details der _transfer() Funktion**
In der `_transfer()` Funktion des ERC-404 Smart Contracts wird diese Logik umgesetzt. Hier wird geprüft, ob der Token-Betrag ganzzahlig oder mit Dezimalstellen ist, und entsprechend umgesetzt:
**Ganzzahliger Betrag:** Der gesamte Betrag wird als ein einzelnes NFT behandelt.
**Dezimalbetrag:** Der Betrag wird in zwei Teile aufgeteilt:
- Ein Teil als ganzer ERC-721 Token.
- Ein anderer Teil als ERC-20 Token, der den Dezimalanteil darstellt.
Diese Logik stellt sicher, dass Benutzer entweder ganze NFTs oder Bruchteile davon in Form von fungiblen Tokens (ERC20) erhalten. Dadurch wird die Interoperabilität und Handbarkeit von NFTs im DeFi-Bereich verbessert.
`// Burn für bestimmte Adressen überspringen, um Gas zu sparen
if (!whitelist [from]) {
uint256 tokens_to_burn = (balanceBeforeSender / unit)
(balance0f [from] / unit);
for (uint256 i = 0; i < tokens_to_burn; i++) {
_burn(from);
}
}
if (!whitelist [from]) {
uint256 tokens_to_mint = (balanceOf[to] / unit)
(balanceBeforeReceiver / unit);
for (uint256 i = 0; i < tokens_to_mint; i++) {
_mint(to);
}
}`
**Wichtige Hinweise zum ERC-404 Token-Standard**
Der ERC-404 Contract erbt nicht von ERC-20 oder ERC-721. Stattdessen handelt es sich um einen neu entwickelten Smart Contract, der Funktionen und Mechanismen seiner Vorgänger implementiert.
**Wichtige Punkte:**
- **Neuer Smart Contract:** Der ERC-404 Contract ist eigenständig und nicht von ERC-20 oder ERC-721 abgeleitet. Er integriert jedoch deren Funktionen und Mechaniken.
- **Experimentell und nicht geprüft:** ERC-404 Tokens sind experimentell und wurden noch nicht auditiert. Sie haben keine Ethereum Improvement Proposal (EIP) und sind daher momentan nicht von allen Protokollen anerkannt.
- **Sicherheitsrisiken:** Da sie nicht vollständig geprüft sind, weisen ERC-404 Tokens mehrere Sicherheitslücken auf, die später im Artikel beschrieben werden.
- **Keine Token-IDs:** Im Gegensatz zu ERC-721 Tokens, die eindeutige Token-IDs besitzen, haben ERC-404 Tokens keine Token-IDs, ähnlich wie ERC-20 Tokens.
**Zusammenfassung**
Der ERC-404 Token-Standard kombiniert zwar die Funktionen von ERC-20 und ERC-721, ist jedoch ein eigenständiger Contract ohne direkte Vererbung von diesen Standards. Aufgrund seines experimentellen Charakters und fehlender Audits bestehen derzeit Sicherheitsrisiken und Kompatibilitätsprobleme mit bestehenden Protokollen.
**Anwendungsfälle des ERC-404 Token-Standards**
Die ersten ERC-404 Tokens wurden in diesem Jahr veröffentlicht, und es gibt bereits mehr als 20 solcher Tokens mit einer Gesamtkapitalisierung von über 300 Millionen Dollar (Stand: März 2024). Schauen wir uns an, wie diese Tokens genutzt werden können.
**Reale Vermögenswerte (RWAs)**
ERC-404 Tokens erleichtern den Handel und den Kauf realer Vermögenswerte, wie zum Beispiel Häuser oder Luxusprodukte. Benutzer können Bruchteile teurer und illiquider Tokens besitzen, was den Handel vereinfacht und die Möglichkeit eröffnet, zusätzliche Erträge zu erzielen.
**Dezentrale Finanzen (DeFi)**
Der Hauptgrund ist, dass NFTs durch ERC-404 Tokens liquider werden und als Sicherheiten für Kredite und Darlehen oder als Liquidität für Protokolle genutzt werden können. Dies eröffnet eine Vielzahl neuer Investitionsmöglichkeiten in dApps.
**Gaming**
Da In-Game-Assets fraktioniert werden, haben Entwickler mehr Freiheit bei der Gestaltung von Spielmechaniken und -ökonomien. Für Benutzer wird es einfacher, In-Game-Assets zu kaufen und zu handeln.
**Zusammenfassung**
Der ERC-404 Token-Standard bietet vielfältige Anwendungsmöglichkeiten in verschiedenen Bereichen. Er ermöglicht den Handel mit realen Vermögenswerten, verbessert die Liquidität von NFTs für den Einsatz in DeFi-Protokollen und vereinfacht den Handel von In-Game-Assets in der Gaming-Industrie.
**Reale Beispiele für ERC-404 Tokens**
Die drei bekanntesten ERC-404 Kollektionen sind derzeit Pandora, DeFrogs und Monkees. Schauen wir uns Pandora genauer an — es war der allererste ERC-404 Token und umfasst 10.000 NFTs, die mit weiteren 10.000 ERC-20 Tokens verknüpft sind. Beim Minten eines PANDORA-Tokens erhalten Benutzer 1 NFT.
**Mechanismus von Pandora**
- **Threshold:** Es gibt eine festgelegte Schwelle, wie viele Tokens jeder Benutzer haben darf. Wenn ein Benutzer mehr als die festgelegte Anzahl besitzt, erhält er ein neu gemintetes NFT. Besitzt er weniger, wird das NFT verbrannt.
- **Wert und Seltenheit:** Dieses ständige Minten und Verbrennen von Tokens erneuert den Wert und die Seltenheit jedes Non-Fungible Tokens.
**Technische Umsetzung**
Früher im Artikel haben wir einen Ausschnitt aus dem ERC-404 Vertrag gezeigt, der speziell für Pandora verwendet wird. Dieser Codeabschnitt enthält eine spezifische Buchführung, die überprüft, ob das NFT eines Benutzers gemintet oder verbrannt werden soll.
**Zusammenfassung**
Pandora ist ein bahnbrechendes Beispiel für die Nutzung des ERC-404 Token-Standards. Durch das ständige Minten und Verbrennen wird der Wert und die Seltenheit der NFTs dynamisch gehalten, was die Attraktivität und den Handelswert dieser Tokens erhöht.
**Sicherheitsüberlegungen zum ERC-404 Token-Standard**
Der ERC-404 Token-Standard ist noch experimentell und nicht vollständig mit bestehenden Protokollen kompatibel. Daher gibt es zwei Hauptprobleme, die beachtet werden sollten:
- **Unklare Standards und Mechaniken:** Viele Entwickler sind nicht ausreichend über den ERC-404 Token-Standard informiert, und es gibt keine formale Ethereum Improvement Proposal (EIP), die diesen Standard standardisiert. In der Zukunft könnten sich daher erhebliche Unterschiede in den Mechanismen der ERC-404 Tokens ergeben.
- **Inkompatibilität mit Protokollen:** Aktuelle Protokolle können nicht zu 100 % genau mit solchen Tokens arbeiten. Dies eröffnet eine Vielzahl von Sicherheitslücken, die mit willkürlichen externen Aufrufen oder einfach fehlerhaften Interaktionen verbunden sind. Solche Schwachstellen können dazu führen, dass Benutzer Geld verlieren, da sie möglicherweise nicht die erwarteten Ergebnisse erzielen.
**Schlussfolgerung**
ERC-404 Tokens haben das Potenzial, eine Innovation im Web3-Bereich darzustellen, indem sie die besten Eigenschaften der beiden Haupt-ERC-Standards kombinieren. Dies eröffnet neue Horizonte für Entwickler und Benutzer, um DeFi besser und benutzerfreundlicher zu gestalten.
Jedoch ist zu beachten, dass ERC-404 derzeit ein experimenteller Standard ist, der ohne formale EIP und mit Inkompatibilitäten zu bestehenden Protokollen kommt. Daher können Benutzer unerwartete Verluste und Fehler erleben, während sie mit solchen Tokens interagieren, und böswillige Akteure haben mehr Möglichkeiten für Angriffe. Es ist wichtig, dass Entwickler und Benutzer sich dieser Risiken bewusst sind und entsprechende Sicherheitsmaßnahmen treffen, um ihre Interaktionen sicher zu gestalten.

Social media can significantly affect divorce proceedings in many ways. To begin, it is no surprise that higher social media usage can cause more issues related to infidelity, jealousy, and overall conflict between the spouses. In today’s digital age, social media is more frequent, and it influences how we connect with others. This is particularly important in the context of a divorce as the usage of online platforms and messaging apps have been a significant cause of marriage breakdown and tension between spouses.
One of the ways social media can impact divorce proceedings is evidence. Any publication or message sent on a social media platform whether it be on Facebook, Instagram, X, or YouTube could be admitted as evidence in court, with respect to one’s rights. From a social media page, one spouse can gather information and insight into the other spouse’s behaviour, lifestyle and interactions with family and friends. These publications would include posts, comments, photos, and messages. Consequently, these elements can be used to prove allegations of infidelity, substance abuse, dishonesty, irresponsible parenting, etc. For example, a spouse may use social media to post pictures of expensive purchases and luxurious travels meanwhile they are refusing to pay child support in the context of their divorce. Social media evidence could influence decisions of the court with respect to parental authority, child custody, partition of assets, child and spousal support.
Moreover, it is important to keep in mind that social media is not always private. With exceptions of a breach of fundamental human rights protected by the Quebec and Canadian Charters of Human Rights and Freedoms, almost any post, comment or photo can be used as evidence in legal proceedings.
Additionally, one can never guarantee the integrity of a social media page, publication, or message. Social media holds a lot of power, and therefore, it is important to reiterate that publications can be taken out of context, misinterpreted or misconstrued. With the popularity of apps like Photoshop, we cannot believe everything we see online.
To ensure that social media does not have a negative effect on divorce proceedings, it is crucial to follow certain guidelines with respect to social media usage, in order to protect yourself during such a vulnerable time.
Firstly, you need to be cautious about what you post online. In other words, you should assume that your posts on social media will be seen by the adverse party and their team.
Secondly, avoid posting about your frustrations, criticisms, and ongoing legal matters with your ex. This also extends to sharing your financial details, your children, and any new relationships online while your divorce proceedings are ongoing.
Lastly, it is important to prioritize your mental health and the protection of your children. Shield them away from the conflict between their parents.
Cooperative and respectful communication will be seen as an advantage before the court. Therefore, it is important to be mindful of what you share on social media platforms. If you have any questions with respect to how social media could affect your individual case, please feel free to contact one of our lawyers here at Spunt Carin who can offer specialized legal advice on the subject.

Hello Crawlee community,
We are back with another blog, this time explaining how Crawlee rotates proxies and prevents crawlers from getting blocked.
Proxies vary in quality, speed, reliability, and cost. There are a [few types of proxies](https://blog.apify.com/types-of-proxies/), such as datacenter and residential proxies. Datacenter proxies are cheaper but, on the other hand, more prone to getting blocked, and vice versa with residential proxies.
It is hard for developers to decide which proxy to use while scraping data. We might get blocked if we use [datacenter proxies](https://blog.apify.com/datacenter-proxies-when-to-use-them-and-how-to-make-the-most-of-them/) for low-cost scraping, but residential proxies are sometimes too expensive for bigger projects. Developers need a system that can manage both costs and avoid getting blocked. To manage this, we recently introduced tiered proxies in Crawlee. Let’s take a look at it.
If you like reading this blog, we would be really happy if you gave [Crawlee a star on GitHub!](https://github.com/apify/crawlee/)

## What are tiered proxies?
Tiered proxies are a method of organizing and using different types of proxies based on their quality, speed, reliability, and cost. Tiered proxies allow you to rotate between a mix of proxy types to optimize your scraping activities.
You categorize your proxies into different tiers based on their quality. For example:
- **High-tier proxies**: Fast, reliable, and expensive. Best for critical tasks where you need high performance.
- **Mid-tier proxies**: Moderate speed and reliability. A good balance between cost and performance.
- **Low-tier proxies**: Slow and less reliable but cheap. Useful for less critical tasks or high-volume scraping.
## Features:
- **Tracking errors**: The system monitors errors (e.g. failed requests, retries) for each domain.
- **Adjusting tiers**: Higher-tier proxies are used if a domain shows more errors. Conversely, if a domain performs well with a high-tier proxy, the system will occasionally test lower-tier proxies. If successful, it continues using the lower tier, optimizing costs.
- **Forgetting old errors**: Old errors are given less weight over time, allowing the system to adjust tiers dynamically as proxies' performance changes.
## Working
The `tieredProxyUrls` option in Crawlee's `ProxyConfigurationOptions` allows you to define a list of proxy URLs organized into tiers. Each tier represents a different level of quality, speed, and reliability.
## Usage
**Fallback Mechanism**: Crawlee starts with the first tier of proxies. If proxies in the current tier fail, it will switch to the next tier.
```js
import { CheerioCrawler, ProxyConfiguration } from 'crawlee';
const proxyConfiguration = new ProxyConfiguration({
tieredProxyUrls: [
['http://tier1-proxy1.example.com', 'http://tier1-proxy2.example.com'],
['http://tier2-proxy1.example.com', 'http://tier2-proxy2.example.com'],
['http://tier2-proxy1.example.com', 'http://tier3-proxy2.example.com'],
],
});
const crawler = new CheerioCrawler({
proxyConfiguration,
requestHandler: async ({ request, response }) => {
// Handle the request
},
});
await crawler.addRequests([
{ url: 'https://example.com/critical' },
{ url: 'https://example.com/important' },
{ url: 'https://example.com/regular' },
]);
await crawler.run();
```
## How tiered proxies use Session Pool under the hood
A session pool is a way to manage multiple [sessions](https://crawlee.dev/api/core/class/Session) on a website so you can distribute your requests across them, reducing the chances of being detected and blocked. You can imagine each session like a different human user with its own IP address.
When you use tiered proxies, each proxy tier works with the [session pool](https://crawlee.dev/api/core/class/SessionPool) to enhance request distribution and manage errors effectively.
For each request, the crawler instance asks the `ProxyConfiguration` which proxy it should use. ' ProxyConfiguration` also keeps track of the requests domains, and if it sees more requests being retried or, say, more errors, it returns higher proxy tiers.
In each request, we must pass `sessionId` and the request URL to the proxy configuration to get the needed proxy URL from one of the tiers.
Choosing which session to pass is where SessionPool comes in. Session pool automatically creates a pool of sessions, rotates them, and uses one of them without getting blocked and mimicking human-like behavior.
## Conclusion: using proxies efficiently
This inbuilt feature is similar to what Scrapy's `scrapy-rotating-proxies` plugin offers to its users. The tiered proxy configuration dynamically adjusts proxy usage based on real-time performance data, optimizing cost and performance. The session pool ensures requests are distributed across multiple sessions, mimicking human behavior and reducing detection risk.
We hope this gives you a better understanding of how Crawlee manages proxies and sessions to make your scraping tasks more effective.
As always, we welcome your feedback. [Join our developer community on Discord](https://apify.com/discord) to ask any questions about Crawlee or tell us how you use it.

1,904,025 | How an AI Model Works? | Stage 1: Detokenization What it is: The first layer of the model acts as an additional step in... | 0 | 2024-06-28T11:41:38 | https://dev.to/eloy_gonzalez_6/como-funciona-un-modelo-de-ia-128i | ai |
**Stage 1: Detokenization**
**What it is:** The first layer of the model acts as an additional step in converting words into numbers that the model can comprehend.
**How it works:** In models like Pythia, this initial layer operates solely on the current token (the piece of information the model is processing at that moment).
**Importance:** Removing this layer confuses the rest of the model, as it loses immediate context. This stage takes individual tokens and groups them into more meaningful entities, such as a full name.
**Stage 2: Feature Engineering**
**What it is:** This stage involves creating useful features from the data.
**How it works:** The early and middle layers of the model recall facts and enhance the identification of spatial and temporal features.
**Importance:** Features become more complex, progressing from understanding sentence structure to capturing their deeper meaning.
**Stage 3: Prediction Ensemble**
**What it is:** This stage converts semantic features into concrete predictions.
**How it works:** Post midway through the model, a form of "voting" among multiple sub-networks determines the next token (word) to predict.
**Importance:** Prediction neurons increase the probability of certain tokens, while suppression neurons decrease others, ensuring more accurate predictions.
**Stage 4: Residual Refinement**
**What it is:** The final stage fine-tunes and refines predictions.
**How it works:** The last layers of the model contain many suppression neurons that eliminate unnecessary features and adjust confidence in the final prediction.
**Importance:** These neurons refine prediction distributions, ensuring they are neither overly confident nor uncertain. The ordering of layers at the beginning and end is crucial due to the significant changes they can induce. | eloy_gonzalez_6 |
1,904,024 | "Advancing Galaxy Analysis: AI-Powered Detection and Segmentation of Edge-On Galaxies" | Discusses the development of a deep learning algorithm to detect and segment edge-on galaxies in... | 0 | 2024-06-28T11:39:11 | https://dev.to/karla_contreras_1904c68c4/advancing-galaxy-analysis-ai-powered-detection-and-segmentation-of-edge-on-galaxies-48gm | universe, ia |
- Discusses the development of a deep learning algorithm to detect and segment edge-on galaxies in astronomical images. Edge-on galaxies are of great interest in galactic astrophysics due to their unique orientation, which allows for the study of various galactic phenomena.
- The process begins with the selection of a dataset of edge-on spiral galaxies from the Galaxy Zoo project and the corresponding images from the Sloan Digital Sky Survey (SDSS). Approximately 16,000 galaxies were selected and used to train the YOLOv5 algorithm for detection purposes. To isolate galaxies from their backgrounds, the SCSS-Net neural network was used to generate segmentation masks. The algorithm detected 8,000 edge-on galaxies, for which a catalog including their parameters obtained from the SDSS database was compiled.
- The algorithm is structured into three main steps:
Detection: Using the YOLOv5 model, detection boxes of edge-on galaxies are obtained.
Segmentation: Extraction of cutouts of detected galaxies using a U-Net-based architecture.
Post-processing: Generation of segmentation masks and extraction of galaxy parameters for further analysis.
- Initial data were selected from Galaxy Zoo 2, following specific criteria to ensure that the selected galaxies were spiral and edge-on. The selected images were uploaded to the Zooniverse platform for data annotation by volunteers, which allowed for accurate and verifiable annotations. This collaboration enabled the preparation of the data for the development of the machine learning algorithm.
- The paper highlights that most detected galaxies have redshifts between 0.02 and 0.10, with low b/a values (ratio of minor to major axes), and are mostly red, which is consistent with the expected characteristics of edge-on galaxies.
- The methodology demonstrates how combining detection and segmentation algorithms can automate the identification and preparation of galaxies for scientific studies. The integrated approach from raw data to usable scientific results is a significant innovation in galactic astrophysics.
- Concludes that the algorithm is not only capable of detecting and segmenting edge-on galaxies with high precision but can also be applied to data from future astronomical surveys, extending its utility and application in future galactic studies.
- This work represents a significant advance in the application of artificial intelligence techniques for analyzing large volumes of astronomical data, facilitating the identification and study of edge-on galaxies, which are crucial for better understanding the structure and dynamics of galaxies.

## Mutabilidade VS Imutabilidade <a name="mutabilidade-vs-imutabilidade">
No JavaScript, diferentes tipos de dados (data types em inglês) têm diferentes comportamentos e locais na memória. Portanto, **para reduzir as chances de ter bugs em seu código**, você precisa entender o conceito de mutabilidade e imutabilidade em JavaScript.
**Mutabilidade** refere-se a tipos de dados que podem ser acessados e alterados após serem criados e armazenados na memória. A **imutabilidade**, por outro lado, refere-se a tipos de dados que não podem ser alterados após a criação, mas que ainda podem ser acessados na memória.
---------------------------------------------------------------
## Data Types <a name="data-types">
Os tipos de dados (data types em inglês) são categorizados em **tipos primitivos** e **de referência** no JavaScript. Antes de explicar essas categorias, vamos dar uma olhada em dois termos importantes relacionados à memória que você precisará conhecer: a **Stack** e a **Heap**.
### O que é a Stack? <a name="o-que-e-stack">
A Stack (pilha em português) é uma estrutura de dados que obedece ao princípio **Last In First Out (LIFO)**. Isso significa que o último item a entrar na pilha sai primeiro.
_Imagem acima da Wikipédia._
### O que é Heap? <a name="o-que-e-heap">
O **Heap** é usado apenas em variáveis do `tipo de dados de referência`.
O **Heap** guarda o **valor real** atribuído à variável. A variável guarda o endereço de memória do Heap. Quando o valor é atribuído à variável, a variável (armazenando o endereço de memória do Heap) é colocada na pilha por cima, por último.
### Tipos de dados primitivos <a name="tipos-de-dados-primitivos">
Os tipos de dados primitivos são imutáveis e não são objetos porque não têm propriedades e métodos: `string`, `number`, `BigInt`, `boolean`, `undefined`, `Symbol`, `null`.
🤔 Espere um minuto, você pode pensar – eu mudo os valores das variáveis primitivas o tempo todo!
Bem, pode parecer que você está modificando um valor, mas esse não é realmente o caso. Vamos mostrar um exemplo:
```javascript
let greet = "Hello";
greet += ", World";
console.log(greet); // Hello, World
```
A primeira linha deste código cria a string `Hello` e a atribui à variável `greet`. A segunda linha anexa `, World` a essa string. Parece que estamos mudando a string `greet`, mas o JavaScript não altera a string, em vez disso, ele cria uma nova string.
### Tipos de dados de referência <a name="tipos-de-dados-referencia">
Por padrão, os `tipos de dados de referência` **são mutáveis**. Os tipos de dados de referência consistem em **funções**, **arrays** e **objetos**.
Os `tipos de dados de referência` colocam a variável na **stack**. A variável funciona como um ponteiro que aponta para o objeto localizado na **heap**.
A principal diferença entre essas categorias é que os **tipos primitivos são `imutáveis`**, mas os **tipos de referência são `mutáveis`**.
---------------------------------------------------------------
## Mutabilidade no JavaScript <a name="mutabilidade-no-javascript">
Se um tipo de dado for mutável, significa que você pode alterá-lo. A mutabilidade permite que você modifique os valores existentes sem criar novos valores.
Para cada **objeto**, um ponteiro é adicionado à `stack`, e esse ponteiro aponta para o **objeto** no `heap`.
Veja, por exemplo, o código a seguir:
```javascript
const person = {
name: "Mike Shinoda",
age: 47,
Hobbies: ["cantar", "tocar guitarra"]
}
```
Na **stack**, você encontrará `person`, que é um ponteiro para o objeto real no **heap**.
```javascript
const person2 = person
console.log(person)
console.log(person2)
```
Outro ponteiro é colocado na **stack** quando `person` é atribuído a `person2`. Agora, **esses ponteiros apontam para um único objeto** no **heap**.
Os dados de referência **não copiam valores**, mas sim **ponteiros**.
```javascript
person2.age = 53;
console.log(person)
console.log(person2)
```
Alterar a idade de `person2` atualiza a idade do objeto `person`. Agora você sabe que isso ocorre **porque ambos apontam para o mesmo objeto**.
-----------------------------------------------------------------
## Como clonar propriedades de objetos <a name="como-clonar-propriedades-de-objetos">
O método `object.assign` copia propriedades de um objeto (a origem) para outro objeto (o destino) e retorna o objeto de destino modificado.
Veja a seguir a sintaxe:
```javascript
Object.assign(target, source)
```
O método tem dois argumentos, `target` e `source`. O `target` é o objeto que recebe as novas propriedades, enquanto a `source` é de onde vêm as propriedades. O `target` pode ser um objeto vazio `{}`.
Em uma situação em que o `source` e o `target` compartilham a mesma chave (key em inglês), o objeto de origem substitui o valor da chave no `target`.
```javascript
const person = {
name: "Mike Shinoda",
age: 47,
Hobbies: ["cantar", "tocar guitarra"]
}
const person2 = Object.assign({}, person);
```
As propriedades do objeto `person` foram clonadas em um `target` vazio.
`person2` agora tem suas próprias propriedades. Você pode comprovar isso alterando o valor de qualquer uma de suas propriedades. Essa alteração não afetará os valores das propriedades do objeto de `person`.
O valor de `person2.age` que foi alterado para 53 não afeta de forma alguma o valor de `person.age` porque ambos têm suas próprias propriedades.
### Usando o Spread Operator <a name="usando-o-spread-operator">
Esta é a sintaxe do Spread Operator:
```javascript
const newObj = {...obj}
```
Usar o operador `spread` é bastante simples. Você precisa colocar três pontos `...` antes do nome do objeto cujas propriedades você pretende clonar:
```javascript
const person = {
name: "Mike Shinoda",
age: 47,
Hobbies: ["cantar", "tocar guitarra"]
}
const person2 = {...person};
person2.age = 53;
console.log(person)
console.log(person2)
```
-----------------------------------------------------------------
## Imutabilidade no JavaScript <a name="imutabilidade-no-javascript">
Imutabilidade é o estado em que os valores são imutáveis (ou seja, não podem ser alterados). Um valor é imutável quando é impossível alterá-lo. Os tipos de dados primitivos são imutáveis, como discutimos acima.
Vamos dar uma olhada em um exemplo:
```javascript
let student1 = "Maiqui";
let student2 = student1;
```
No código acima, uma variável chamada `student1` foi criada e atribuída a `student2`.
```javascript
student1 = "Mike"
console.log(student1);
console.log(student2)
```
A alteração de `student1` para `Mike` não altera o valor inicial de `student2`. Isso prova que, nos tipos de dados primitivos, os valores reais são copiados, portanto, ambos têm seus próprios valores. Na memória **stack**, `student1` e `student2` são diferentes.
A **stack** obedece ao princípio **Last-In-First-Out** (último a entrar, primeiro a sair). O primeiro item que entra na **stack** é o último a sair e vice-versa. Assim, acessar aos itens armazenados na **stack** fica fácil.
-----------------------------------------------------------------
## Como evitar a mutabilidade de objetos <a name="como-evitar-a-mutabilidade-de-objetos">
Até agora, você aprendeu que os **objetos são mutáveis por padrão**.
```javascript
const people = {
person1: 'Mike',
person2: 'Chester',
person3: 'Joe'
}
Object.defineProperty(people, "person4", {
value: "Brad",
})
console.log(people);
```
Agora adicionamos o `person4`.
Para evitar a mutabilidade do objeto, você pode usar os métodos `Object.preventExtensions()`, `Object.seal()` e `Object.freeze()`.
Para todos os três métodos, exploraremos a **adição de propriedades** usando a `notação de ponto` e a propriedade `define`, a **modificação de propriedades** usando `defineProperty` e a **exclusão de propriedades**.
Isso lhe dará uma melhor compreensão dos recursos e das limitações de cada método e, por fim, o ajudará a determinar qual método é mais adequado para um caso de uso específico.
Portanto, vamos nos aprofundar e explorar esses métodos com mais detalhes.
### Como usar o método `Object.preventExtensions` <a name="como-usar-o-metodo-object-prevent-extensions">
Veja a seguir a sintaxe desse método:
```javascript
Object.preventExtensions(obj)
```
O uso do `Object.preventExtensions` **impede que novas propriedades entrem no objeto**. O objeto não aumenta de tamanho e mantém suas propriedades. **Por padrão, todos os objetos em JavaScript são extensíveis**. Com esse método, você pode excluir propriedades do seu objeto.
#### Tentando adicionar novas propriedades (`Object.preventExtensions`)
* usando a `notação de ponto (dot notation)`:
```javascript
const makeNonExtensive = {
firstname: "Maiqui",
lastname: "Tomé"
}
Object.preventExtensions(makeNonExtensive)
makeNonExtensive.designation = "Software Engineer";
console.log(makeNonExtensive)
```
Verifique o console - a propriedade `designation` não foi adicionada e não há nenhuma mensagem de erro:
* usando o método `defineProperty`
Aqui está a sintaxe:
```javascript
Object.defineProperty(obj, prop, descriptor)
```
Veja o que está acontecendo no código acima:
1. `obj`: O objeto ao qual você deseja adicionar propriedades.
2. `prop`: Você define o nome da propriedade que deseja adicionar ou alterar. Deve ser uma cadeia de caracteres ou um símbolo
3. `descriptor`: você inclui o valor da propriedade.
```javascript
const makeNonExtensive = {
firstname: "Maiqui",
lastname: "Tomé"
}
Object.preventExtensions(makeNonExtensive)
Object.defineProperty(makeNonExtensive, "age", {
value: 18,
})
console.log(makeNonExtensive)
```
A **adição de novas propriedades** usando a propriedade `define` gera esta mensagem de erro: `Uncaught TypeError: Cannot define property age, object is not extensible`
#### Como modificar uma propriedade existente usando `defineProperty` (`Object.preventExtensions`)
```javascript
const makeNonExtensive = {
firstname: "Maiqui",
lastname: "Tomé"
}
Object.preventExtensions(makeNonExtensive)
Object.defineProperty(makeNonExtensive, 'firstname', {
value: 'Mike',
})
console.log(makeNonExtensive)
```
O valor da propriedade de um objeto não extensível pode ser alterado:
#### Como excluir uma propriedade (`Object.preventExtensions`)
Aqui está a sintaxe:
```javascript
delete object.propertyname
```
```javascript
const makeNonExtensive = {
firstname: "Maiqui",
lastname: "Tomé"
}
Object.preventExtensions(makeNonExtensive)
delete makeNonExtensive.lastname
console.log(makeNonExtensive)
```
Apesar de o objeto não ser extensível, a propriedade `lastname` foi excluída:
### Como usar o método `Object.seal()` <a name="como-usar-o-metodo-object-seal">
Todos os objetos em Javascript são extensíveis por padrão. Como o nome sugere, esse método **sela** um objeto. Não é possível adicionar novas propriedades a um objeto selado ou excluir uma propriedade existente de um objeto selado. Mas o `object.seal` permite modificar as propriedades existentes.
Aqui está a sintaxe:
```javascript
Object.seal(obj)
```
#### Como adicionar novas propriedades (`Object.seal()`)
```javascript
const people = {
person1: 'Maiqui',
person2: "Maria",
person3: "Eduardo"
}
Object.seal(people)
console.log(Object.isSealed(people))
```
`Object.isSealed(people)` é usado para verificar se um objeto está selado.
* Como usar a `notação de ponto`
```javascript
people.person4 = "Patrick"
console.log(people)
```
**Sem produzir um erro**, a `notação de ponto` **falha** ao adicionar a nova propriedade `person4`:
* Usando o método `defineProperty` (`Object.seal()`)
```javascript
const people = {
person1: 'Maiqui',
person2: "Maria",
person3: "Eduardo"
}
Object.seal(people)
Object.defineProperty(people, 'person4', {
value: 'Patrick'
})
console.log(people)
```
A mensagem de erro `"Uncaught TypeError: Cannot define property student4, the object is not extendable"` é lançada quando se tenta adicionar a mesma propriedade usando o método `defineProperty`.
#### Como modificar uma propriedade existente usando `defineProperty` (`Object.seal()`)
```javascript
const people = {
person1: 'Maiqui',
person2: "Maria",
person3: "Eduardo"
}
Object.seal(people)
Object.defineProperty(people, 'person2', {
value: 'Maria Clara',
})
console.log(people)
```
Agora, o `person2` foi alterado de `"Maria"` para `"Maria Clara"`:
#### Tentando remover uma propriedade existente (`Object.seal()`)
```javascript
const people = {
person1: 'Maiqui',
person2: "Maria",
person3: "Eduardo"
}
Object.seal(people)
delete people.person1
console.log(people)
```
As propriedades não podem ser removidas dos objetos selados. No console, `person1` ainda permanece:
### Como usar o método `Object.freeze()` <a name="como-usar-o-metodo-object-freeze">
Aqui está a sintaxe:
```javascript
Object.freeze(obj)
```
O método `Object.freeze()` congela um objeto. O uso desse método **garante alta integridade** ao assegurar que não será possível extrair, modificar propriedades existentes ou adicionar novas propriedades ao objeto.
Para verificar se um objeto está congelado, use a sintaxe abaixo:
```javascript
Object.isFrozen(obj);
```
> **ATENÇÃO** 🚨
Mesmo quando você aplica o `Object.freeze()` a um objeto, é possível adicionar uma nova propriedade, modificar uma propriedade existente ou excluir propriedades de objetos **aninhados sob ele**.
Assim como fizemos com outros métodos, vamos explorar o método `Object.freeze()` em relação à adição de novas propriedades, modificação de valores ou exclusão de propriedades de um objeto.
#### Tentando adicionar novas propriedades (`Object.freeze()`)
* Usando `dot notation`
```javascript
const sportClubInternacional = {
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré"
}
Object.freeze(sportClubInternacional)
sportClubInternacional.player4 = "Alan Patrick"
console.log(sportClubInternacional)
```
Observe que o `player4` não foi adicionado:
* Usando o método `defineProperty`
```javascript
const sportClubInternacional = {
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré"
}
Object.freeze(sportClubInternacional)
Object.defineProperty(sportClubInternacional, 'player4', {
value: "Alan Patrick"
})
console.log(sportClubInternacional)
```
A notação de ponto falha silenciosamente ao tentar adicionar uma propriedade, mas `defineproperty` gera um `TypeError`:
#### Tentando modificar propriedades (`Object.freeze()`)
```javascript
const sportClubInternacional = {
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré"
}
Object.freeze(sportClubInternacional)
sportClubInternacional.player1 = "Enner Valencia - Atacante"
console.log(sportClubInternacional)
```
O código acima falhou silenciosamente, mas com a propriedade `defineProperty` abaixo, um `typeError` é lançado.
```javascript
const sportClubInternacional = {
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré"
}
Object.freeze(sportClubInternacional)
Object.defineProperty(sportClubInternacional, 'player1', {
value: "Enner Valencia - Atacante"
})
console.log(sportClubInternacional)
```
#### Tentando deletar propriedades (`Object.freeze()`)
```javascript
const sportClubInternacional = {
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré"
}
Object.freeze(sportClubInternacional)
delete sportClubInternacional.player1
console.log(sportClubInternacional)
```
A tentativa de excluir uma propriedade em um objeto congelado também falha silenciosamente:
--------------------------------------------------------
## Como usar Deep Freeze <a name="como-usar-deep-freeze">
```javascript
const sportClubInternacional = {
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré",
substitutes: {
player4: "Lucas Alario",
player5: "Thiago Maia"
}
}
Object.freeze(sportClubInternacional)
Object.defineProperty(sportClubInternacional.substitutes, 'player6', {
value: "Alan Patrick"
})
console.log(sportClubInternacional)
```
O `player6` foi adicionado aos `substitutos aninhados`, embora o método `Object.freeze()` tenha sido aplicado aos jogadores da equipe principal.
#### Deletando o jogador reserva aninhado
```javascript
const sportClubInternacional = {
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré",
substitutes: {
player4: "Lucas Alario",
player5: "Thiago Maia"
}
}
Object.freeze(sportClubInternacional)
delete sportClubInternacional.substitutes.player5
console.log(sportClubInternacional)
```
O `player5` foi removido. Tudo o que o `object.freeze` impede no objeto pai pode ser feito no objeto filho que está aninhado:
Para evitar isso, empregamos a técnica de congelamento profundo (Deep Freeze em inglês), conforme mostrado abaixo:
#### Aplicando o Deep Freeze
```javascript
const deepVal = obj => {
Object.keys(obj).forEach(prop => {
if (typeof obj[prop] === 'object') deepVal(obj[prop]);
});
return Object.freeze(obj);
};
const sportClubInternacional = deepVal({
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré",
substitutes: {
player4: "Lucas Alario",
player5: "Thiago Maia"
}
})
Object.freeze(sportClubInternacional)
console.log(Object.isFrozen(sportClubInternacional));
```
#### Tentando adicionar uma nova propriedade ao objeto filho
```javascript
const deepVal = obj => {
Object.keys(obj).forEach(prop => {
if (typeof obj[prop] === 'object') deepVal(obj[prop]);
});
return Object.freeze(obj);
};
const sportClubInternacional = deepVal({
player1: "Enner Valencia",
player2: "Sergio Rochet",
player3: "Rafael Borré",
substitutes: {
player4: "Lucas Alario",
player5: "Thiago Maia"
}
})
Object.freeze(sportClubInternacional)
Object.defineProperty(sportClubInternacional.substitutes, 'player6', {
value: "Alan Patrick"
})
console.log(sportClubInternacional);
```
Agora, quando você tentar adicionar uma propriedade, receberá este erro `Uncaught TypeError: Cannot define property player6, object is not extensible`:
Além disso, o Deep Freeze também impede que você altere e exclua propriedades de um objeto.
--------------------------------------------------------
## Como evitar a mutabilidade de arrays <a name="como-evitar-a-mutabilidade-de-arrays">
A mutabilidade em arrays segue o mesmo princípio dos objetos. Vou mostrar aqui só um exemplo pois é bem parecido com os exemplos de objetos já que ambos são `tipos de dados de referência`:
--------------------------------------------------------
## Considerações finais <a name="considerações-finais">
Neste artigo você viu sobre os vários tipos de dados e se eles são imutáveis ou mutáveis por padrão.
Você viu que quando você usa `const` você deve se preocupar com os `tipos de dados de referencia` que são mutáveis.
Os objetos podem ser alterados por padrão. Mas o uso de métodos específicos, como `Object.seal`, `Object.freeze` e `preventExtensions`, pode impedir a mutabilidade.
O nível de imutabilidade fornecido por esses métodos varia, portanto, certifique-se de usar aquele que corresponde ao nível de integridade que você deseja atingir.
Era isso... obrigado por ler e até a próxima 🙂👋

1,903,951 | Types of state management | Introduction State management is a critical aspect of software development, enabling... | 0 | 2024-06-28T11:31:23 | https://dev.to/wafa_bergaoui/types-of-state-management-23d0 | frontend, react, development, javascript | ## **Introduction**
State management is a critical aspect of software development, enabling applications to handle data consistently and efficiently. This guide explores various state management approaches, types, and best practices across different frameworks and libraries, providing a holistic understanding of the topic.
## **Types of State Management**
**1. Centralized State Management**
Centralized state management involves storing the entire application's state in a single, centralized store. This approach ensures a single source of truth, making it easier to manage and debug the state.
**Example**: Redux (React)
Redux is a popular centralized state management library for React applications. It uses a single store to manage the entire state and follows a strict unidirectional data flow.
```javascript
import { createStore } from 'redux';
// Reducer function
function counterReducer(state = { count: 0 }, action) {
switch (action.type) {
case 'INCREMENT':
return { count: state.count + 1 };
default:
return state;
}
}
// Create store
const store = createStore(counterReducer);
// Dispatch actions
store.dispatch({ type: 'INCREMENT' });
console.log(store.getState()); // { count: 1 }
```
## **2. Reactive State Management**
Reactive state management allows state to be updated automatically in response to changes, typically using observables or reactive programming principles. This approach is particularly useful for real-time applications.
**Example:** MobX (React)
MobX is a library that enables reactive state management using observable state and reactions.
```javascript
import { observable, action } from 'mobx';
class Store {
@observable count = 0;
@action increment() {
this.count++;
}
}
const store = new Store();
store.increment();
console.log(store.count); // 1
```
**3. Atomic State Management**
Atomic state management breaks the state into small, independent units (atoms) that can be managed and updated individually. This approach allows for fine-grained control over the state.
**Example:** Recoil (React)
Recoil is a state management library for React that uses atoms to represent state pieces.
```javascript
import { atom, useRecoilState } from 'recoil';
// Atom
const countState = atom({
key: 'countState',
default: 0,
});
function Counter() {
const [count, setCount] = useRecoilState(countState);
return (
<div>
<p>Count: {count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
```
## **Categories of State**
**1. Local State**
Local state is confined to a single component and managed internally using hooks like useState in React or state variables in other frameworks.
**Example:** React useState
```javascript
import React, { useState } from 'react';
function Counter() {
const [count, setCount] = useState(0);
return (
<div>
<p>Count: {count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
```
**2. Global State**
Global state is shared across multiple components and managed using context or global stores.
**Example:** React Context API
```javascript
import React, { createContext, useContext, useState } from 'react';
const CountContext = createContext();
function CountProvider({ children }) {
const [count, setCount] = useState(0);
return (
<CountContext.Provider value={{ count, setCount }}>
{children}
</CountContext.Provider>
);
}
function Counter() {
const { count, setCount } = useContext(CountContext);
return (
<div>
<p>Count: {count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
function App() {
return (
<CountProvider>
<Counter />
</CountProvider>
);
}
```
**3. Server State**
Server state refers to data fetched from a server that needs to be synchronized with the client state. Tools like React Query and SWR are used to manage server state effectively.
**Example:** React Query
```javascript
import { useQuery } from 'react-query';
function fetchCount() {
return fetch('/api/count').then((res) => res.json());
}
function Counter() {
const { data, error, isLoading } = useQuery('count', fetchCount);
if (isLoading) return <div>Loading...</div>;
if (error) return <div>Error loading count</div>;
return <div>Count: {data.count}</div>;
}
```
**4. Form State**
Form state manages data within form components, including user input and validation states.
**Example:** Formik (React)
```javascript
import { useFormik } from 'formik';
function MyForm() {
const formik = useFormik({
initialValues: { email: '' },
onSubmit: values => {
console.log(values);
},
});
return (
<form onSubmit={formik.handleSubmit}>
<input
name="email"
type="email"
onChange={formik.handleChange}
value={formik.values.email}
/>
<button type="submit">Submit</button>
</form>
);
}
```
**Best Practices for State Management**
**- Keep State Minimal:** Only store the necessary state to avoid complexity.
**- Use Derived State:** Compute derived state from existing state instead of storing redundant data.
**- Encapsulate State:** Encapsulate state management logic to keep components clean and focused on UI rendering.

### What is Dijkstra's Algorithm? 🤔
Dijkstra's Algorithm, named after its creator Edsger W. Dijkstra, is used to solve the shortest path problem for a graph with non-negative edge weights. It finds the shortest path from a source vertex to all other vertices in the graph.
### How Does Dijkstra's Algorithm Work? 🛠️
The algorithm works by iteratively selecting the vertex with the smallest known distance from the source and updating the distances of its neighboring vertices. Here’s a step-by-step explanation:
1. **Initialization**:
- Set the distance to the source node to zero and to all other nodes to infinity.
- Mark all nodes as unvisited. Create a set of all the unvisited nodes called the unvisited set.
- Set the initial node as the current node.
2. **Visit Neighboring Nodes**:
- For the current node, consider all its unvisited neighbors and calculate their tentative distances through the current node. Compare the newly calculated tentative distance to the current assigned value and assign the smaller one. For example, if the current node A is marked with a distance of 6, and the edge connecting it with a neighbor B has a length of 2, then the distance to B through A will be 6 + 2 = 8. If B was previously marked with a distance greater than 8 then change it to 8. If the neighboring node has already been visited, skip it.
3. **Mark the Current Node as Visited**:
- Once all neighbors of the current node have been visited, mark the current node as visited. A visited node will not be checked again.
4. **Select the Next Current Node**:
- Select the unvisited node with the smallest tentative distance and set it as the new "current node", then go back to step 2.
5. **Repeat**:
- Repeat steps 2-4 until all nodes have been visited. By then, the shortest path to all nodes will have been found.
### Example with Visual Illustration 🌟
Consider the graph illustrated below with the following edges and weights:
The edges and their weights are:
- A to B: 4
- A to C: 5
- B to D: 9
- B to C: 11
- C to E: 3
- D to E: 13
- D to F: 2
- E to F: 6
Let's find the shortest path from A to all other nodes.
1. **Initialization**:
- Distance: A=0, B=∞, C=∞, D=∞, E=∞, F=∞
- Unvisited set: {A, B, C, D, E, F}
- Current node: A
2. **Visit Neighbors of A**:
- Update distance for B: Distance[B] = 0 + 4 = 4
- Update distance for C: Distance[C] = 0 + 5 = 5
- Distance: A=0, B=4, C=5, D=∞, E=∞, F=∞
3. **Mark A as Visited**:
- Unvisited set: {B, C, D, E, F}
4. **Select B as the Next Current Node**:
- Current node: B
5. **Visit Neighbors of B**:
- Update distance for D: Distance[D] = 4 + 9 = 13
- Update distance for C: Distance[C] = min(5, 4 + 11) = 5
- Distance: A=0, B=4, C=5, D=13, E=∞, F=∞
6. **Mark B as Visited**:
- Unvisited set: {C, D, E, F}
7. **Select C as the Next Current Node**:
- Current node: C
8. **Visit Neighbors of C**:
- Update distance for E: Distance[E] = 5 + 3 = 8
- Distance: A=0, B=4, C=5, D=13, E=8, F=∞
9. **Mark C as Visited**:
- Unvisited set: {D, E, F}
10. **Select E as the Next Current Node**:
- Current node: E
11. **Visit Neighbors of E**:
- Update distance for F: Distance[F] = 8 + 6 = 14
- Distance: A=0, B=4, C=5, D=13, E=8, F=14
12. **Mark E as Visited**:
- Unvisited set: {D, F}
13. **Select D as the Next Current Node**:
- Current node: D
14. **Visit Neighbors of D**:
- Update distance for F: Distance[F] = min(14, 13 + 2) = 15
- Distance: A=0, B=4, C=5, D=13, E=8, F=14
15. **Mark D as Visited**:
- Unvisited set: {F}
16. **Select F as the Next Current Node**:
- Current node: F
17. **Mark F as Visited**:
- Unvisited set: {}
At this point, all nodes have been visited, and the shortest distances from A are:
- A to B: 4
- A to C: 5
- A to D: 13
- A to E: 8
- A to F: 14
### Python Implementation 🐍
Here’s a Python implementation of Dijkstra's Algorithm:
```python
import heapq
def dijkstra(graph, start):
# Priority queue to store (distance, node)
priority_queue = [(0, start)]
# Dictionary to store the shortest path to each node
shortest_paths = {start: (None, 0)}
visited = set()
while priority_queue:
current_distance, current_node = heapq.heappop(priority_queue)
if current_node in visited:
continue
visited.add(current_node)
for neighbor, weight in graph[current_node].items():
distance = current_distance + weight
if neighbor not in shortest_paths or distance < shortest_paths[neighbor][1]:
shortest_paths[neighbor] = (current_node, distance)
heapq.heappush(priority_queue, (distance, neighbor))
return shortest_paths
# Define the graph
graph = {
'A': {'B': 4, 'C': 5},
'B': {'D': 9, 'C': 11},
'C': {'E': 3},
'D': {'E': 13, 'F': 2},
'E': {'F': 6},
'F': {}
}
# Compute the shortest paths
start_node = 'A'
shortest_paths = dijkstra(graph, start_node)
# Output the shortest paths
for node, (prev, dist) in shortest_paths.items():
path = []
current = node
while current:
path.append(current)
current = shortest_paths[current][0]
path.reverse()
print(f"Shortest path to {node}: {dist}, Path: {' -> '.join(path)}")
```
### Conclusion 🎉
Dijkstra's Algorithm is a powerful tool for finding the shortest path in a weighted graph. By understanding and implementing this algorithm, you can solve various real-world problems, such as network routing, geographic mapping, and more. With this detailed explanation and example, you should now have a solid grasp of how Dijkstra's Algorithm works and how to apply it in your own projects.

You... | 0 | 2024-06-28T11:29:03 | https://dev.to/pepper_square/conducting-a-ux-audit-and-how-it-can-lead-your-business-to-success-4g0m | If you run a business online, you know how difficult it is to get those conversion numbers high. You see a decline in the numbers; you hit the drawing board with your team and try to find out what to fix. But how do you know what exactly is wrong with your website or app?
The best way to keep abreast of how users feel about your product is to gather feedback. But apart from feedback from users and information gathered through data, you and your team can analyze the user experience of your product and see if something can be fixed, which is called conducting a UX audit. Let’s talk a little more about how you can fill in the gaps with a user experience audit.
## What is a UX audit?
Just as a company audits finances and employee performances regularly, it is important to audit design standards and user experience of its products too. Every business, at some point in time, finds itself in a sea of problems and needs a way to find solutions for them. UX reports after audits are used to spot imperfections and inadequacies of the website or app.
The best part about user experience audits is that they can be conducted for businesses as small as a startup with an app in the making or as large as a multinational company with several flagship products to showcase.
Some key questions are answered during a UI/UX audit:
1. Is there any friction in the user journey? Where are the points of friction?
2. Where, on the platform, is the drop-off rate the highest?
3. Is the information presented to the users ample enough to help them make decisions?
4. Does the interface design follow heuristic principles?
It is essentially a cumulative assessment of the usefulness, usability, aesthetics, value, experience, and user-friendliness of a website or app.
UX audits generally provide a much more in-depth insight into the issues of the product than heuristic evaluations. Not that it has to be said out loud, but the bad user experience is a hole in the money ship for a company. Lately, almost all companies have started investing in user experience in order to increase profits since they understand that bad design does not work well. Such audits or analyses can help strategize and nudge a business in the right direction by solving real user problems.
## When should you conduct a UX audit?
An audit could be conducted, usually, at two points in the design process – during the design process, called the formative assessment, and after the product has been developed, called the summative assessment.
It is a good practice to conduct design audits as regularly as possible to sanitize your products and keep the vision on track to success. In an agile environment, usability testing, heuristic evaluations, etc., happen frequently to take into account user pain points and eliminate them at the earliest. In the same way, UX assessments should also be frequent.
## Objectives and Outcomes
In order to successfully perform a UX website audit, a prerequisite is to list the goals clearly. For instance, if your website is seeing low conversion rates, your UX audit goals could be analyzing the website to improve metrics like conversion rate, bounce rate, and drop-offs.
Accumulating relevant metrics is not an easy task. All stakeholders involved within the team should put their heads together to find these. Some of the most common metrics are – NPS (net promoter score), task success rate, bounce rate, user engagement rates, time on task, conversion rate, CSAT (customer satisfaction), and SUS (system usability scale).
Some frequently used techniques to collect these metrics are:
**Heuristic evaluation:** Evaluating or auditing your product’s interface against an industry-standard checklist to empathize with the user and make their experience better. Instead of basing your criteria on your own parameters, it is best to incorporate widely used parameters like Neilsen’s 10 usability heuristics.
**Analytics:** Heuristic evaluation is more for qualitative assessment. For quantitative assessment of how your product is doing, data speaks volumes, literally. If you track data on your website using tools like Google Analytics, then you will find tons of data points to validate your hypothesis and form assumptions.
**Sales figures:** Not recommended due to heavy human intervention, but sales figures can sometimes tell you things other techniques cannot, since your sales staff generally stay in touch with the clients a lot more than your design team. They may even conduct surveys and interviews that can inform your decisions.
**Previous audits:** If your company or team has already conducted audits in the past, you can use that to your advantage. Keeping the metrics similar to the previous audit with a few extra additions from learnings can make it simpler to find issues and fix them.
Deliverables of a website’s UX audit are usually compiled in a properly structured report containing a detailed description of the audit goals, techniques used, results and even suggestions or strategies.
## What are the benefits of a UX Audit for business?
With its objectives and outcomes signaling benefits, it’s important that we track down and explore the main advantages. The following points highlight the need for a UX audit and how your business will change once the audit is conducted.
**Data backed redesign**
A lack of data could be a cause for concern as businesses scramble for solutions. However, UX audit brings in factual data and also advises you on what tools that you need to be using.
It does a complete review of the business and suggests ways that you can improve and raise the rate of conversion. By the end of the user experience audit, you will be aware of what’s holding your business back.
Hence, factual data does change the game for good.
**Competitive advantage**
UX audits also help you draw comparisons with similar products or services and keep you informed on why they are ahead of you. By also looking at examples and case studies, you can further understand how these comparisons can benefit your business.
With benchmark analysis in place, you can also understand what prompts customers to choose your competitor.
**Improved user satisfaction**
A complete UX audit brings in product cognitive walkthroughs to help you get closer to a user’s perspective. This analysis helps you compare your product with the goals of users and shows areas where you can improve.
The qualitative and quantitative data that you receive from this analysis further help you examine how your product tracks down user behavior.
**Cost saving**
The improvement plan that comes with UX audits helps you transition to the redesigning phase and suggests improvements only in fields where you can genuinely increase the value.
UX audits, although they can change the template, they don’t go out of their way to increase costs. In fact, in the past, UX audits are known to help cut costs and thus open the pathway to make more profits.
As your product or service rises in value, people tend to understand it faster, and helps you eliminate all distractions that may stand in the way of conversions. With the product being more intuitive, purchase requests could rise, and thus profits could al
so go up.
Hence, the development phase will only begin with necessary additions that don’t include changes for problems that can’t be identified. As a result, wrong decisions will be out of the picture and spending will be constrained.
**Increased conversions**
A better user experience can lead to increased conversions, such as more sign-ups, downloads, or sales. This in turn will improve the user experience, and help increase customer retention, increase conversions, such as more sign-ups, downloads, or sales, and reduce churn.
**Better engagement**
A product with a better user experience can lead to increased engagement, such as longer session times and more interactions.
## How does one conduct a UX audit?
A user experience audit can be conducted in phases since there are a lot of moving parts involved.
**Preparation**
Before you even begin conducting the analysis, it is important to prepare for it. Gathering relevant metrics as mentioned before, charting out phases, allotting enough time to each phase, and choosing the evaluating team are all part of preparation. Having the right strategy can save time and money while resulting in extremely useful output.
**Outlining business objectives**
Although all UX designers in a company are advocates for the users, business objectives take the front seat in a UX audit along with user goals. Interviewing stakeholders of all kinds like the sales team, business development team, consumer service team, and design and development team can help you align your UX audit checklist with the company’s business goals.
**Familiarisation with users**
Never in your entire design process, be it research, designing, or testing, should you not keep in mind your user personas. After all, everything you do as a designer is to make the product better for your users. If you are new to the project, familiarise yourself with the user personas and even conduct some interviews. You will gain a lot of qualitative insight from user interviews.
You may be tempted to drag the interview series for a lot longer due to the active participation of the users, but it is recommended to limit your sessions to 5-10 users and interview them fairly similarly.
**Outlining user objectives**
At every stage of this audit, you will be able to identify some user stories. These user stories present opportunities and ultimately get converted into user flows that help users successfully complete tasks on your website or app.
You can also add more information to your user personas at this stage too since you will gather a lot of intel from the previous phases. As and when you can, write down user stories and map journeys.
**Inspect analytics**
Concrete evidence of bad UX can be found in analytics. As discussed earlier, if you are monitoring data on your website through tools like Google Analytics or Hotjar, you can closely pinpoint areas of improvement.
If the budget permits, a data science team can be coherently used with the design team to keep track of metrics from time to time and make reports. These reports essentially provide trends and patterns of user behavior, which may be used to refine their journey.
**Conduct a heuristic evaluation**
There’s enough to talk about heuristic evaluations as a whole new blog. In this phase, experts come together with certain parameters or design heuristics to assess the product interface.
Keeping users updated with the system status, engineering for errors, flexibility and efficiency of use, decluttered minimal design, and jargon-less designs are some heuristics to follow. There are some commonly used standard checklists like the aforementioned Neilsen’s 10 usability heuristics and Shneiderman’s 8 golden UI rules.
Even though heuristic evaluation is the assessment of a product’s UI, its objective is to find usability issues and areas of UX improvement. Better usability results in better user engagement, which ultimately results in an increased return on investment.
**Compile a report and suggest strategies**
The last phase is perhaps the most important in the UX audit process. Once all techniques have been exhausted and enough findings have been collected, a compilation of these findings to be shared with the entire team is an important step.
One thing to be noted here is to compile findings in the most effective way possible, avoiding extremely complex pieces of information. Better ways to convey insights would be through design deliverable pieces like wireframes, prototypes, annotated visual designs, etc.
Any sort of UX report should be followed with suggestions around how the findings can be put to use in the best way possible to improve the overall experience of the product. Instead of giving the report a negative connotation of things going wrong, it would be better to give it a more positive tone of improving and heading forward. Suggested strategies should also be practical and achievable by the resources at hand, and divided into appropriate priorities.
## Tips to perform a successful UX audit
- **Recording relevant information**
A UX audit is going to bring out all kinds of information and keep you updated with the latest from the world of user experience. These will contain relevant information and also irrelevant information.
Grouping them and categorizing one into relevant data is not enough because you also need to record said data. In this manner, you create a huge source of information that will benefit you as you move along.
- **Suggest recommendations**
UX audits are bound to come back with suggestions to make minor to massive design improvements. That means there is an added onus upon the agency to keep all stakeholders in the loop. Since time and tide waits for none, you will have to start immediately and take charge of all that needs to be done.
- **Prioritize**
Prioritizing your findings is quite important to help you get on track and match the level of your competitor. By doing so, you can also cut costs and stay away from performing tasks that don’t require one’s attention and tasks that don’t contribute anything of value.
So keep all your stakeholders informed about what needs to be prioritized and what can come later.
- **Quick evaluations**
The recommendations that come from UX audits need to be evaluated and understood effectively. Merely going through them without having to understand what value comes from them will not help your business achieve your targets.
Moreover, you shouldn’t blindly follow top UI/UX design trends for everyone. That is a crowd mentality and won’t lead to stellar outcomes. A quick yet thorough analysis is needed to complete the auditing process.
- **Remember your goals and objectives**
With the urge to stay up to date being pivotal, businesses have the urge to quickly conduct UX audits and update everything. Doing so will not yield immediate results because you haven’t aligned these changes with your goals and objectives.
So as a business organization, you should always remember your goals and objectives and then move forward to utilize the results of the UX audit.
<u>**Takeaway**</u>
This article has been a beginner’s guide to helping you understand what a UX audit is, how to conduct and how it benefits your business. With these steps in mind, you have the right template that goes out to solve all your current problems.
So now that we’ve discussed the UX audit process in depth, it is time for you to conduct your own audit and deliver a world-class experience to your users. If you are in need of expert guidance, contact our team at Pepper Square for a UX and UI audit.

3. Give it a name, e.g., MyBarcodeScanningApp.
4. Choose **Storyboard** as the interface.
5. Select **Swift** as the programming language.
Next, we’ll install the Barcode Scanner SDK package.
## Installing the SDK
For this tutorial, we will use the [Swift Package Manager](https://developer.apple.com/documentation/xcode/swift-packages) to install the Barcode Scanner SDK.
1. In Xcode, go to **File -> Add Package Dependencies…**
2. Paste the following package URL into the search bar: https://github.com/doo/scanbot-barcode-scanner-sdk-ios-spm.git
3. Select the package and click **Add Package**.
4. In the pop-up that appears after verification, for “Add to Target”, choose your project.
5. Click **Add Package** again.
> 💡 Without a license key, our SDK only runs for 60 seconds per session. This is more than enough for the purposes of our tutorial, but if you like, you can [generate a license key here](https://scanbot.io/trial/).
>
> For more information about where to put the license key in your code, please refer to [SDK Initialization](https://docs.scanbot.io/document-scanner-sdk/ios/sdk-initialization/) in our docs.
We’ll need access to the device camera to scan barcodes, so let’s set the corresponding privacy property now.
In the project navigator, select your project, then select your app under “TARGETS”. Open the tab **Info**, add the target property **Privacy – Camera Usage Description**, and type in a meaningful value, e.g., “Grant access to your camera to start scanning”.
## Integrating the scanning functionalities
Now that the project is set up, integrating barcode scanning into your app is very straightforward.
In fact, it’s so straightforward that we’ll implement not just one, but **three different scanning modes** in our project:
- **Single-barcode scanning:** Read and show the value of a single barcode.
- **Multi-barcode scanning:** Read as many barcodes as you like and display their values in a list.
- **AR overlay:** Display the values of the barcodes in the viewfinder on the screen in real time.
Here’s how we’re going to achieve that:
- **Step 1:** Set up the main screen (create three buttons and connect them to our View Controller)
- **Step 2:** Implement the scanning modes (copy and paste the code for the three scanning modes into the @IBAction functions)
- **Step 2.5 (optional):** Customize the scanning UI
- **Step 3:** Start scanning 🤳
Let’s dive right in!
## Step 1: Setting up the main screen
How exactly you approach this is up to you, but for the sake of this tutorial, we will just add three `UIButton` elements (“Single-Barcode Scanning”, “Multi-Barcode Scanning”, and “AR Overlay”) onto the View Controller Scene in **Main.storyboard**. Then, we connect them as an **Action** to **ViewController.swift** by dragging them while holding the **control** key.
For our purposes, let’s call the resulting `@IBAction` functions “startSingleScanning”, “startMultiScanning”, and “startAROverlay”.
We also need to import the ScanbotBarcodeScannerSDK package like so:
```
import ScanbotBarcodeScannerSDK
```
In the next step, we’ll add the code to get our scanning interface up and running into those functions.
## Step 2: Implementing the scanning modes
Thanks to our [RTU UI components](https://docs.scanbot.io/barcode-scanner-sdk/ios/barcode-scanner/ready-to-use-ui/), integrating our Barcode Scanner SDK’s features into your app is a breeze!
In fact, you can just copy and paste the code from our [documentation](https://docs.scanbot.io/barcode-scanner-sdk/ios/barcode-scanner/ready-to-use-ui/#use-cases) 🦥
Here’s the code to put in each function for your convenience:
**For single-barcode scanning:**
```
...
@IBAction func startSingleScanning(_ sender: Any) {
// Create the default configuration object.
// Create the default configuration object.
let configuration = SBSDKUI2BarcodeScannerConfiguration()
// Initialize the single-scan use case.
let singleUsecase = SBSDKUI2SingleScanningMode()
// Enable and configure the confirmation sheet.
singleUsecase.confirmationSheetEnabled = true
singleUsecase.sheetColor = SBSDKUI2Color(colorString: "#FFFFFF")
// Hide/unhide the barcode image of the confirmation sheet.
singleUsecase.barcodeImageVisible = true
// Configure the barcode title of the confirmation sheet.
singleUsecase.barcodeTitle.visible = true
singleUsecase.barcodeTitle.color = SBSDKUI2Color(colorString: "#000000")
// Configure the barcode subtitle of the confirmation sheet.
singleUsecase.barcodeSubtitle.visible = true
singleUsecase.barcodeSubtitle.color = SBSDKUI2Color(colorString: "#000000")
// Configure the cancel button of the confirmation sheet.
singleUsecase.cancelButton.text = "Close"
singleUsecase.cancelButton.foreground.color = SBSDKUI2Color(colorString: "#C8193C")
singleUsecase.cancelButton.background.fillColor = SBSDKUI2Color(colorString: "#00000000")
// Configure the submit button of the confirmation sheet.
singleUsecase.submitButton.text = "Submit"
singleUsecase.submitButton.foreground.color = SBSDKUI2Color(colorString: "#FFFFFF")
singleUsecase.submitButton.background.fillColor = SBSDKUI2Color(colorString: "#C8193C")
// Set the configured use case.
configuration.useCase = singleUsecase
// Create and set an array of accepted barcode formats.
configuration.recognizerConfiguration.barcodeFormats = SBSDKUI2BarcodeFormat.twoDFormats
// Present the recognizer view controller modally on this view controller.
SBSDKUI2BarcodeScannerViewController.present(on: self,
configuration: configuration) { controller, cancelled, error, result in
// Completion handler to process the result.
// The `cancelled` parameter indicates whether the cancel button was tapped.
controller.presentingViewController?.dismiss(animated: true)
}
...
```
**For multi-barcode scanning:**
```
...
@IBAction func startMultiScanning(_ sender: Any) {
// Create the default configuration object.
let configuration = SBSDKUI2BarcodeScannerConfiguration()
// Initialize the multi-scan use case.
let multiUsecase = SBSDKUI2MultipleScanningMode()
// Set the counting repeat delay.
multiUsecase.countingRepeatDelay = 1000
// Set the counting mode.
multiUsecase.mode = .counting
// Set the sheet mode of the barcodes preview.
multiUsecase.sheet.mode = .collapsedSheet
// Set the height of the collapsed sheet.
multiUsecase.sheet.collapsedVisibleHeight = .large
// Enable manual count change.
multiUsecase.sheetContent.manualCountChangeEnabled = true
// Configure the submit button.
multiUsecase.sheetContent.submitButton.text = "Submit"
multiUsecase.sheetContent.submitButton.foreground.color = SBSDKUI2Color(colorString: "#000000")
// Set the configured use case.
configuration.useCase = multiUsecase
// Create and set an array of accepted barcode formats.
configuration.recognizerConfiguration.barcodeFormats = SBSDKUI2BarcodeFormat.twoDFormats
// Present the recognizer view controller modally on this view controller.
SBSDKUI2BarcodeScannerViewController.present(on: self,
configuration: configuration) { controller, cancelled, error, result in
// Completion handler to process the result.
// The `cancelled` parameter indicates whether the cancel button was tapped.
controller.presentingViewController?.dismiss(animated: true)
}
...
```
**For the AR overlay:**
```
...
@IBAction func startAROverlay(_ sender: Any) {
// Create the default configuration ject.
let configuration = SBSDKUI2BarcodeScannerConfiguration()
// Configure the usecase.
let usecase = SBSDKUI2MultipleScanningMode()
usecase.mode = .unique
usecase.sheet.mode = .collapsedSheet
usecase.sheet.collapsedVisibleHeight = .small
// Configure AR Overlay.
usecase.arOverlay.visible = true
usecase.arOverlay.automaticSelectionEnabled = false
// Set the configured usecase.
configuration.useCase = usecase
// Create and set an array of accepted barcode formats.
configuration.recognizerConfiguration.barcodeFormats = SBSDKUI2BarcodeFormat.twoDFormats
// Present the recognizer view controller modally on this view controller.
SBSDKUI2BarcodeScannerViewController.present(on: self,
configuration: configuration) { controller, cancelled, error, result in
// Completion handler to process the result.
// The `cancelled` parameter indicates whether the cancel button was tapped.
controller.presentingViewController?.dismiss(animated: true)
}
}
}
```
There’s one tiny thing we’ll change here right away, though: We want to be able to scan both 1D and 2D barcode formats.
For this, let’s go to `configuration.recognizerConfiguration.barcodeFormats` in each `@IBAction` function and change `SBSDKUI2BarcodeFormat.twoDFormats` to `SBSDKUI2BarcodeFormat.commonFormats`.
Let’s now explore some of the other customization options.
## Step 2.5 (optional): Customizing the scanning UI
Our RTU UI not only makes it very easy to integrate our SDK’s scanning functionalities, but also to style the UI elements in any way you like 🎨
(Well, maybe not in ANY way. Sorry, Bob.)
The comments already give you a hint about what’s possible to change:
- Hide or show specific UI elements
- Configure the active and inactive states of some UI elements
- Change colors
- Change titles and subtitles
- Change the accepted barcode formats
- Control the barcode sheet behavior for multi-scanning
- … and more
As an example, let’s take a closer look at some of the configuration options of our multi-barcode scanning feature:
```
// Set the counting mode.
multiUsecase.mode = .counting
```
Here, we can change `.counting` to `.unique`. This will prevent the SDK from scanning multiple barcodes with the same value, which is helpful if you only want to count the number of _unique_ barcodes.
```
// Set the sheet mode of the barcodes preview.
multiUsecase.sheet.mode = .collapsedSheet
```
Change `.collapsedSheet` to `.button` to not show the upper part of the barcode results sheet at the bottom of the screen and display a button that calls up the sheet instead.
> 💡 You can change the entire RTU UI’s color scheme using the [palette feature](https://docs.scanbot.io/barcode-scanner-sdk/ios/barcode-scanner/ready-to-use-ui/#palette).
Once you’ve made your changes, build and run your app.
## Step 3: Scanning some barcodes!
Now you can go ahead and scan 1D and 2D barcodes – one after the other, many at the same time, and even with an AR overlay that lets you preview their values!
If you’re in need of some barcodes, we’ve got you covered:
If this tutorial has piqued your interest in integrating barcode scanning functionalities into your iOS app, make sure to take a look at our SDK’s other features in our [documentation](https://docs.scanbot.io/barcode-scanner-sdk/ios/barcode-scanner/ready-to-use-ui/).

1,904,001 | Exploring Leverage Trading with Cryptocurrencies | In the dynamic world of cryptocurrency app development, opportunities arise for those who seek to... | 0 | 2024-06-28T11:20:11 | https://dev.to/donnajohnson88/exploring-leverage-trading-with-cryptocurrencies-214b | cryptocurrency, trading, learning, cryptodevelopment | In the dynamic world of [cryptocurrency app development](https://blockchain.oodles.io/cryptocurrency-development-services/?utm_source=devto), opportunities arise for those who seek to maximize their investment returns. One strategy that has gained significant popularity and attention is leverage trading with cryptocurrency. This powerful technique allows traders to increase their market exposure, potentially magnifying profits — but it comes with its own set of risks. Leverage trading in cryptocurrencies is borrowing money from a broker to boost your capital’s trading potential. Leverage is the term for this amplification factor, and it has a ratio representation. With a 10x leverage, for example, you may take ownership of a position that is worth ten times your initial investment.
## The Benefits of Leverage Trading
**Magnified Profits**
Leverage allows traders to control a larger position size with a smaller amount of capital. As a result, profitable trades can yield higher returns compared to trading with just the available capital.
**Increased Market Exposure**
Leverage enables traders to gain exposure to larger market movements with a smaller upfront investment. It gives traders access to a wider variety of markets and instruments, opening up new trading opportunities.
## The Risks of Leverage Trading
**Increased Risk of Loss**
Leverage may greatly boost earnings, but it can also greatly raise losses. Traders may lose a lot of money very rapidly, maybe more than they originally invested.
**Margin Calls**
In leveraged positions, a drop in the market value of an asset may lead to a margin call, requiring the trader to either deposit more funds or risk having the initial position/funds forcibly closed.
**Market Volatility Impact**
Leveraged holdings are more likely to experience liquidation events when there is high market volatility, which can cause fast price fluctuations.
**Complexity and Skill Requirement**
Leverage trading is complex and requires a deep understanding of risk management and finance. New traders may find it challenging to navigate through the complexities of leveraged positions.
Many crypto exchanges provide leverage trading functionality. It’s essential for traders to carefully evaluate each platform, considering factors such as leverage options, user interface, security features, and available trading pairs. **Now, let’s explore some of the well-known platforms in the cryptocurrency space that provide leveraged trading features.**
**Vela**
It is available for Arbitrum and Base network. To participate in trading, we are required to deposit USDC in their perpetual wallet. It supports all Bitcoin (BTC)Ethereum (ETH), USDT, USDC, BNB, DAI, LINK, DOT, UNI, SUSHI, and many more tokens.
**ApolloX**
It is available for Arbitrum and the BNB network. To participate in trading, an initial deposit is required.
**GMX**
It is available for Arbitrum and Avalanche networks and a limited selection of tokens, including BTC, ETH, ARB, LINK, SOL, UNI, DOGE, XRP, and LTC.
**Apex**
This platform only supports the following tokens and requires an initial deposit before trading can commence: BTC, ETH, AAVE, PEPE, ARB, XRP, ATOM, DOGE, and MATIC.
**dYdX**
It supports ETH exclusively.
**MUX**
While it offers a good range of tokens, approximately 53, it does come with slightly higher fees.
**Binance**
Binance provides leveraging on the following tokens, BTC, ETH, BNB, 1inch, Aave, ADA, BCH, Dot, EOS, FIL, LInk, LTC, Sushi, SX, TRX, UNI, XLM, XRP, XTZ, YFI
## Conclusion
Crypto leverage trading is a powerful tool that can amplify both profits and losses. It is essential to approach leverage trading with caution, understanding the inherent risks, and implementing effective risk management strategies. Before attempting leverage trading, novice traders should acquire experience in conventional bitcoin trading.

When it comes to softwares, I have always been fascinated about how things work under the hood. This is the reason I chose this career path. I started my tech journey in web development. I learnt and used the MERN (MongoDB, ExpressJS, ReactJS, NodeJS) to create multiple fullstack web applications.
I realised at some point that I might enjoy mobile development. So I decided to give it a try and learnt Flutter. This was one of the best decisions I made as I got my first real software developer job as a mobile app developer. I currently work as the senior mobile application engineer of a fintech company using Flutter.
## No Room for Complacency
If you are as passionate about softwares, this wouldn't come as a shocker to you. I am always looking to learning new things and upgrading my skills.
I decided to pick up Go language. Although I have little experience in backend development with NodeJS|ExpressJS and MongoDB, this was a while ago and I'm a little bit rusty. I decided to learn backend development in Go and PostgreSQL. I realised I have that same feeling I had when I decided to venture into mobile development with Flutter. I realised I enjoy backend development, especially in Go. This is my current stage now, as I am still learning; although I have built a mini [project](https://github.com/JamiuJimoh/ChecklistsServer) in this stack.
## Interlude
I recently learnt about the [HNG](https://hng.tech/internship) internship and I thought to myself, "this couldn't have come at a better time". I learnt the [internship](https://hng.tech/premium) is for anyone and any developer at any role and with any level of experience. It is a platform to learn and collaborate with minds alike. It also offers exposures to job opportunities. I am genuinely grateful for this opportunity and I'm looking to making the most out of it.

Whether you’re applying for a loan, renting an apartment, or simply tracking your earnings, having accurate pay stubs is a must. However, not everyone has access to professional payroll services or pay stub generators. That’s where the “Zero to Pay Stub Hero” DIY approach comes in.
In this guide, we’ll walk you through the steps to create your [free pay stub generator](https://stubcreator.com/pay-stub-generator/), ensuring they’re not only accurate but also meet the standards required for various financial and personal needs.
## Understanding the Importance of Pay Stubs
Before we dive into the DIY approach, it’s crucial to understand why pay stubs matter. A pay stub is a document that outlines your earnings, deductions, and other financial details related to your employment.
## Here’s why pay stubs are essential:
Proof of Income: Pay stubs serve as concrete proof of your income, which is often required when applying for loans, renting apartments, or even applying for certain jobs.
Budgeting: Having a clear breakdown of your income and deductions helps you manage your finances better and plan your budget effectively.
Tax Compliance: Pay stubs provide information on taxes withheld, aiding in accurate tax filing and preventing potential issues with the IRS.
Legal Requirements: Some states and employers have legal requirements for providing pay stubs to employees. Knowing your rights is essential.
## Gathering the Necessary Information
To create your pay stubs, you’ll need to gather some essential information and documents.
## Here’s what you’ll need:
Personal Information: Start by collecting your details, including your full name, address, and Social Security Number (SSN).
Employment Details: Gather information about your employer, such as the company name, address, and contact information.
Payroll Records: Collect your recent pay statements, as these will serve as a reference for creating your pay stubs.
Tax Information: Ensure you have accurate information about your federal and state tax withholding, including your filing status.
## Choosing the Right DIY Tools
Creating pay stubs from scratch can be a daunting task, but thanks to various online resources, it’s now more accessible than ever.
Here are some free DIY tools and resources you can use:
Pay Stub Templates: Many websites offer free pay stub templates that you can customize to suit your needs. Look for user-friendly templates that allow you to input your information accurately.
Online Pay Stub Generators: Several online pay stub generators are designed to help you create professional-looking pay stubs quickly. These tools often come with step-by-step instructions, making the process easier.
Spreadsheet Software: If you’re comfortable with spreadsheet software like Microsoft Excel or Google Sheets, you can create your pay stubs manually. There are templates available online to help you get started.
## Creating Your Pay Stubs
Now that you have the necessary information and tools let’s walk through the process of creating your pay stubs:
Select a Template: If you’re using a pay stub template or online generator, choose one that matches your needs. Ensure it includes fields for your personal information, employment details, income, deductions, and taxes.
Enter Your Information: Carefully input all the required information into the template. Double-check for accuracy, as errors can lead to financial complications later.
Calculate Taxes: If your template doesn’t automatically calculate taxes, use the tax information you gathered to determine the correct amounts for federal and state taxes. Be sure to follow the latest tax regulations.
Review and Save: Once you’ve entered all the details, review your pay stub to ensure accuracy. Save it as a PDF or print a hard copy for your records.
## Pay Stub Best Practices
To ensure your DIY pay stubs meet industry standards and avoid potential issues, follow these best practices:
Accuracy is Key: Double-check all the information on your pay stub to ensure it’s accurate and up-to-date.
Stay Informed: Keep yourself informed about tax laws and regulations in your state to ensure your pay stubs comply with current requirements.
Save Copies: Maintain a record of your pay stubs for at least three years, as they may be needed for future reference or verification.
Use Legible Fonts: When customizing your pay stubs, choose legible fonts and formatting to ensure clarity and professionalism.
## When to Seek Professional Help
While the DIY approach is excellent for many individuals, there are situations where professional assistance is advisable:
Self-Employment: If you’re self-employed, handling pay stubs can be more complex due to various income sources and tax considerations. Consult a tax professional in such cases.
Legal Matters: If you encounter legal issues related to your employment or income, consult an attorney who specializes in employment law.
Complex Tax Situations: If your tax situation is intricate, such as owing back taxes or dealing with multiple income sources, seek advice from a tax expert.
Conclusion
Becoming a “Pay Stub” doesn’t require fancy software or expensive services. With the right information and free DIY tools, you can create accurate and [professional pay stubs](https://stubcreator.com/pay-stub-generator/) that meet your financial and personal needs. | ada_langer_e91fcfe2945672 | |
1,903,994 | How to Create Objects in JavaScript | Creating objects in JavaScript is fundamental to programming in the language. Objects are collections... | 0 | 2024-06-28T11:17:16 | https://dev.to/oluwadamisisamuel1/how-to-create-objects-in-javascript-1l9 | webdev, javascript, programming, beginners | Creating objects in JavaScript is fundamental to programming in the language. Objects are collections of key-value pairs, where each key is a string (also called a property), and each value can be anything, including other objects, arrays, or functions. This article will cover several ways to create objects in JavaScript, providing clear examples for each method.
## 1. Object Literals
The simplest way to create an object in JavaScript is by using an object literal. This method is straightforward and concise.
```
const person = {
name: "John Doe",
age: 30,
greet: function() {
console.log("Hello, my name is " + this.name);
}
};
// Accessing properties and methods
console.log(person.name); // Output: John Doe
person.greet(); // Output: Hello, my name is John Doe
```
In the example above, person is an object with properties name and age, and a method greet.
## 2. The new Object() Syntax
Another way to create an object is by using the new Object() syntax. This approach is less common but serves the same purpose.
```
const car = new Object();
car.make = "Toyota";
car.model = "Camry";
car.year = 2020;
console.log(car.make); // Output: Toyota
```
This method initializes an empty object and then assigns properties to it.
## 3. Using a Constructor Function
For creating multiple objects of the same type, you can use a constructor function. Constructor functions are a template for creating objects.
```
function Person(name, age) {
this.name = name;
this.age = age;
this.greet = function() {
console.log("Hello, my name is " + this.name);
};
}
const john = new Person("John Doe", 30);
const jane = new Person("Jane Doe", 28);
john.greet(); // Output: Hello, my name is John Doe
jane.greet(); // Output: Hello, my name is Jane Doe
```
Here, Person is a constructor function that initializes new Person objects with specified name and age properties.
## 4. The Object.create() Method
The Object.create() method creates a new object with a specified prototype object and properties.
```
const personProto = {
greet: function() {
console.log("Hello, my name is " + this.name);
}
};
const person1 = Object.create(personProto);
person1.name = "John Doe";
person1.age = 30;
person1.greet(); // Output: Hello, my name is John Doe
```
In this example, person1 is created with personProto as its prototype, inheriting the greet method.
## 5. Classes (ES6)
ES6 introduced classes, which provide a clearer and more concise way to create objects and handle inheritance.
```
class Person {
constructor(name, age) {
this.name = name;
this.age = age;
}
greet() {
console.log("Hello, my name is " + this.name);
}
}
const john = new Person("John Doe", 30);
const jane = new Person("Jane Doe", 28);
john.greet(); // Output: Hello, my name is John Doe
jane.greet(); // Output: Hello, my name is Jane Doe
```
Classes make the code more readable and resemble other object-oriented languages like Java or C#.
## 6. Using Factory Functions
Factory functions are another pattern for creating objects. These functions return new objects without using new.
```
function createPerson(name, age) {
return {
name: name,
age: age,
greet: function() {
console.log("Hello, my name is " + this.name);
}
};
}
const john = createPerson("John Doe", 30);
const jane = createPerson("Jane Doe", 28);
john.greet(); // Output: Hello, my name is John Doe
jane.greet(); // Output: Hello, my name is Jane Doe
```
Factory functions are flexible and can include additional logic to initialize the objects.
## Summary
In JavaScript, there are multiple ways to create objects, each suited to different scenarios:
- Object Literals: Best for simple and single objects.
- new Object(): A less common, verbose alternative.
- Constructor Functions: Useful for creating many similar objects.
- Object.create(): Ideal for prototypal inheritance.
- Classes (ES6): Provides a clear, concise syntax for creating objects and handling inheritance.
- Factory Functions: Flexible functions that return new objects.
Each method has its own advantages and use cases. Understanding these methods allows you to choose the best one for your particular programming needs.

1,903,988 | Comparing Svelte and Solid.js: Niche Frontend Technologies Explored | There are several frameworks and libraries available in the dynamic field of frontend development... | 0 | 2024-06-28T11:11:48 | https://dev.to/anyidollar/comparing-svelte-and-solidjs-niche-frontend-technologies-explored-4fho | There are several frameworks and libraries available in the dynamic field of frontend development that are intended to optimize application performance and improve the developer experience. Even while ReactJS is still the industry standard, especially in the context of the HNG Internship program, there are a few specialized technologies that are worth investigating. This essay focuses on two cutting-edge frontend technologies—Svelte and Solid.js—that provide unique methods for creating user interfaces. We'll contrast their features, emphasize their special benefits, and talk about why ReactJS is still a useful tool in the HNG setting.
Svelte: An Optimized Web Application Compiler
Rich Harris's Svelte framework is a significant departure from more conventional frameworks like React and Vue. It functions as a compiler, transforming declarative elements into extremely effective imperative code that works directly with the DOM.
Crucial Elements of Svelte:
No Virtual DOM: Svelte forgoes the use of a virtual DOM in favor of optimizing JavaScript, which updates the DOM directly and offers faster performance.
Built-in Reactivity: Svelte's reactivity paradigm is seamlessly incorporated into the language, making state management easier to understand and encouraging code that is cleaner and easier to maintain.
Reduced Bundle Sizes: Svelte apps usually have reduced bundle sizes because they do not require a framework runtime, which improves load times and overall performance.
When to Use Svelte: Projects requiring high performance and effective state management are especially well-suited for Svelte. Because of its distinct methodology, it's perfect for developing interactive web apps that are as efficient and simple to use as possible.
Solid.js: Fine-Grained Control with High-Performance Reactivity
The Ryan Carniato-developed Solid.js offers a distinctive blend of React-like declarative language and Svelte-like fine-grained reactivity in a compilation technique.
Essential Elements of Solid.js:
Fine-Grained Reactivity: Even in complicated applications, Solid.js's fine-grained reactivity approach guarantees extremely effective and precisely targeted updates.
Solid.js facilitates JSX syntax, which lowers the learning curve and gives React developers a sense of familiarity.
Direct DOM Manipulation: Solid.js, like Svelte, combines elements to create code that modifies the DOM directly, reducing overhead and optimizing speed.
How to Apply Solid.js:
For developers who value the React paradigm but want the performance advantages of fine-grained reactivity, Solid.js is a great option. It works especially well for tasks that need for intricate communication and state management without sacrificing efficiency.
HNG's ReactJS: A Mainstay for Sturdy Development
ReactJS is an essential technology used in the HNG Internship program because of its robust ecosystem, component-based architecture, and active community.
Benefits of ReactJS for HNG

Huge Ecosystem: Redux, Zustand, and React Router are just a few of the frameworks and tools available in React's ecosystem, which covers a wide range of tasks from state management to routing.
Active Community: There are a lot of resources, tutorials, and best practices available in React's sizable and vibrant community, which promotes ongoing learning and development.
My excitement to work with ReactJS is at an all-time high as I get ready to begin the HNG internship. I've found working with ReactJS to be really fulfilling so far, and I'm forward to see how the internship can enhance this experience even further.
ReactJS has shown to be an incredibly versatile framework, enabling me to take an inventive approach to problem-solving. The development process is now more efficient and simplified because to the component-based design and good state management, which have made it easier to create scalable and maintainable systems.
The HNG Internship provides mentorship and community support, which is something I am especially looking forward to. These resources are really helpful to me in developing my abilities and understanding ReactJS's intricacies. It's a rare opportunity to be a part of a dynamic group of like-minded people with seasoned mentors, and I'm thrilled to take it.
With React's robust features and the encouraging HNG community, I'm sure this internship will help me expand my development skills and make meaningful applications.

**Step 1: Install Required Tools**
First, make sure you have the required tools installed in your Python environment:
```sh
pip install isort black flake8 pre-commit
```
Save the dependencies in your `requirements.txt` file:
```python
# requirements.txt (28.06.2024)
black==24.4.2
flake8==7.1.0
isort==5.13.2
pre-commit==3.7.1
```
**Step 2: Create a Pre-Commit Configuration File**
Create or update a file named `.pre-commit-config.yaml` in the root of your project:
```yml
# .pre-commit-config.yaml (28.06.2024)
repos:
- repo: https://github.com/pre-commit/pre-commit-hooks
rev: v4.6.0
hooks:
- id: trailing-whitespace
- id: end-of-file-fixer
- id: check-added-large-files
- repo: https://github.com/PyCQA/isort
rev: 5.13.2
hooks:
- id: isort
- repo: https://github.com/psf/black
rev: 24.4.2
hooks:
- id: black
- repo: https://github.com/pycqa/flake8

[isort]
profile=black
```
**Step 4: Set up Pre-Commit**
Run the following command to set up the pre-commit hooks:
```sh
pre-commit install
```
This command installs the pre-commit hooks defined in your .pre-commit-config.yaml file. Now, every time you try to commit code, the hooks will run automatically to ensure the code adheres to the specified quality checks and formatting rules.
results in something like:
```sh
(venv) ➜ project git: ✗ pre-commit install
pre-commit installed at .git/hooks/pre-commit
```
**Step 4.1: Update all pre-commit hooks:**
Ensure all hooks are up-to-date by running:
```sh
pre-commit autoupdate
```
**Step 5: Running Pre-Commit Manually (Optional)**
You can also run the pre-commit hooks manually at any time with the following command:
```sh
pre-commit run --all-files
```
By following these steps, you create a robust pre-commit hook system that enforces code quality and style consistency across your Django project. This helps catch issues early and ensures a more maintainable codebase.

1,903,981 | Enhancing Transparency and Accountability: Implementing Entity Audit Logging in Java [Part-2/2] | In the last post, we used io.ebean's ChangeLog annotation to log entity changes in a synchronous... | 27,817 | 2024-06-28T11:01:41 | https://dev.to/anuj-singh1/enhancing-transparency-and-accountability-implementing-entity-audit-logging-in-java-part-22-3gm7 | programming, java | In the last post, we used io.ebean's `ChangeLog` annotation to log entity changes in a synchronous blocking I/O application. In this post, we will see how that works in a multithreaded or async (non-blocking) I/O application.
If your system uses a separate thread-pool or executor context for doing I/O tasks such as making an HTTP API request or a database transaction, then, the audit log prepare class will not be able to detect the user context on model entities that are updated, as the model entity will be saved in a different context or thread-pool. Hence, we need to ensure that the thread-context is not lost when switching the executor or when switching threads in the same thread-pool.
To do so, first we need to understand how to store some data in thread context. For this we will use ThreadLocals. ThreadLocal construct allows us to store data that will be accessible only by a specific thread. Each thread will have its own ThreadLocal instance, hence while switching the context, we need to ensure that the thread context of the current thread is propagated to the next thread.
## STORING USER CONTEXT IN THREAD LOCALS
We can set ThreadLocals with user info and use it in change log prepare’s implementation to set it in change set.
### ThreadLocalManager
```
public class ThreadLocalManager {
private static ThreadLocal<Map<String, Object>> context = new ThreadLocal<>();
public static void addToContext(String key, Object value) {
Map<String, Object> currentContext = ThreadLocalManager.context.get() == null ? new HashMap<>() : context.get();
currentContext.put(key, value);
context.set(currentContext);
}
public static void setContext(Map<String, Object> contextMap) {
context.set(contextMap);
}
public static Map<String, Object> getContext() {
return context.get();
}
public static Object getFromContext(String key) {
return Nullifier.get(() -> context.get().getOrDefault(key, "NA"));
}
public static void clearContext() {
ThreadLocalManager.context.remove();
}
}
```
We can add additional info before setting the thread local
```
ThreadLocalManager.addToContext("userContext", new HashMap<String, String>() {{
put("userName", "some user");
put("userEmail", "some.user@company.com");
}}
entity.save()
```
Now we'll modify our ChangeLogPrepare to read user data from thread context
### Custom ChangeLogPrepare
```
public class AuditLogPrepare implements ChangeLogPrepare {
private final play.Logger.ALogger logger = Logger.of(this.getClass());
@Override
public boolean prepare(ChangeSet changes) {
Map<String, String> userContext = Nullifier.get(() -> (Map<String, String>) ThreadLocalManager.getContext().get("userContext"), new HashMap<>());
if (userContext.isEmpty()) logger.warn("[ALERT] userContext is empty for changeset: " + changes.toString());
changes.getUserContext().put("userName", authMap.getOrDefault("userName", DEFAULT_USER_NAME));
changes.getUserContext().put("userEmail", authMap.getOrDefault("userEmail", DEFAULT_USER_EMAIL));
changes.setSource("MyApp");
return true;
}
}
```
As we see, the user data is taken from thread local, we need to ensure that the thread context is maintained while switching the thread. For that, we'll create a utility class that helps us propagate the thread context to next runnable/callable.
### ContextUtility
```
public class ContextUtility {
public static <T> Callable<T> wrapWithContext(Callable<T> task) {
Map<String, Object> previousContext = ThreadLocalManager.getContext();
if (previousContext == null)
return task;
else
return () -> {
ThreadLocalManager.setContext(previousContext);
try {
return task.call();
} finally {
ThreadLocalManager.clearContext();
}
};
}
public static Runnable wrapWithContext(Runnable task) {
Map<String, Object> previousContext = ThreadLocalManager.getContext();
if (previousContext == null) {
return task;
} else
return () -> {
ThreadLocalManager.setContext(previousContext);
try {
task.run();
} finally {
ThreadLocalManager.clearContext();
}
};
}
}
```
Using the methods from ContextUtility we create CustomThreadPoolExecutor to override methods to attach thread context before submitting/executing tasks
### CustomThreadPoolExecutor
```
public class CustomThreadPoolExecutor extends ThreadPoolExecutor {
public CustomThreadPoolExecutor(int corePoolSize,
int maximumPoolSize,
long keepAliveTime,
@NotNull TimeUnit unit,
@NotNull BlockingQueue<Runnable> workQueue,
@NotNull ThreadFactory threadFactory,
@NotNull RejectedExecutionHandler handler) {
super(corePoolSize, maximumPoolSize, keepAliveTime, unit, workQueue, threadFactory, handler);
}
@Override
public <T> @NotNull Future<T> submit(@NotNull Callable<T> task) {
return super.submit(ContextUtility.wrapWithContext(task));
}
@Override
public <T> @NotNull Future<T> submit(@NotNull Runnable task, T result) {
return super.submit(ContextUtility.wrapWithContext(task), result);
}
@Override
public @NotNull Future<?> submit(@NotNull Runnable task) {
return super.submit(ContextUtility.wrapWithContext(task));
}
@Override
public void execute(@NotNull Runnable task) {
super.execute(ContextUtility.wrapWithContext(task));
}
```
Now, we will use this executor in our custom MDC to allow creating custom dispatchers.
### CustomDispatcherConfigurator
```
public class CustomDispatcherConfigurator extends MessageDispatcherConfigurator {
private final CustomDispatcher instance;
public CustomDispatcherConfigurator(Config config, DispatcherPrerequisites prerequisites) {
super(config, prerequisites);
Config threadPoolConfig = config.getConfig("thread-pool-executor");
int fixedPoolSize = threadPoolConfig.getInt("fixed-pool-size");
instance = new CustomDispatcher(
this,
config.getString("id"),
config.getInt("throughput"),
Duration.create(config.getDuration("throughput-deadline-time", TimeUnit.NANOSECONDS), TimeUnit.NANOSECONDS),
(id, threadFactory) -> () -> new CustomThreadPoolExecutor(fixedPoolSize,
fixedPoolSize,
threadPoolConfig.getDuration("keep-alive-time", TimeUnit.MILLISECONDS),
TimeUnit.MILLISECONDS,
new LinkedBlockingDeque<>(),
new ThreadFactory() {
private int threadId = 1;
@Override
public Thread newThread(@NotNull Runnable r) {
Thread thread = new Thread(r);
thread.setName(config.getString("name") + "-" + threadId++);
return thread;
}
}),
Duration.create(config.getDuration("shutdown-timeout", TimeUnit.MILLISECONDS), TimeUnit.MILLISECONDS)
);
}
@Override
public MessageDispatcher dispatcher() {
return instance;
}
}
class CustomDispatcher extends Dispatcher {
public CustomDispatcher(MessageDispatcherConfigurator _configurator,
String id,
int throughput,
Duration throughputDeadlineTime,
ExecutorServiceFactoryProvider executorServiceFactoryProvider,
scala.concurrent.duration.FiniteDuration shutdownTimeout) {
super(_configurator, id, throughput, throughputDeadlineTime, executorServiceFactoryProvider, shutdownTimeout);
}
}
```
Now we can create different actors in our actor system using this custom MDC and define their config in aplication.conf
```
db-io-dispatcher {
type = "contexts.CustomDispatcherConfigurator"
executor = "thread-pool-executor"
thread-pool-executor {
fixed-pool-size = 11
}
throughput = 1
shutdown-timeout = 60s
}
web-io-dispatcher {
type = "contexts.CustomDispatcherConfigurator"
executor = "thread-pool-executor"
thread-pool-executor {
fixed-pool-size = 20
}
throughput = 1
shutdown-timeout = 60s
}
```
To create an actor for db execution context
### DatabaseIODispatcher
```
public class DatabaseIODispatcher extends CustomExecutionContext {
@Inject
public DatabaseIODispatcher(ActorSystem actorSystem) {
super(actorSystem, "db-io-dispatcher");
}
}
```
This allows us to switch context from one executor to another without losing thread’s context.
## Points to Remember
- In async implementations, if the thread is switched in-between from custom executors to default ThreadPoolExecutor or ForkJoinPool, the thread context will get lost, hence we need to ensure that the thread context is not getting lost if any library method is using default pools.
- We need to clear thread context after the task is complete or else it can cause memory leaks or OOM issues.

1,903,926 | Implementing User Authentication with React Hooks and Firebase | Learn how to use React Hooks and Firebase for building a reliable user authentication system. | 0 | 2024-06-28T10:00:32 | https://dev.to/itselftools/implementing-user-authentication-with-react-hooks-and-firebase-37lk | javascript, react, firebase, authentication |
At [Itself Tools](https://itselftools.com), we've learned a great deal through our journey of developing over 30 dynamic websites using Next.js and Firebase. Today, I'll walk you through an essential piece of functionality if you're considering adding authentication to your React applications: user login using Firebase.
## Understanding the Code
Here is the React hook that facilitates user authentication using Firebase Auth:
```javascript
import { useCallback } from 'react';
import { getAuth, signInWithEmailAndPassword } from 'firebase/auth';
const useLogin = () => {
const auth = getAuth();
const login = useCallback(async (email, password) => {
try {
const userCredential = await signInWithEmailAndPassword(auth, email, password);
return userCredential.user;
} catch (error) {
console.error('Failed to login', error);
throw error;
}
}, [auth]);
return { login };
};
export default useLogin;
```
### Step-by-Step Breakdown
1. **Import Necessary Modules**: We start by importing `useCallback` from React, which will help in memoizing the login function to prevent unnecessary re-renderings. Then, we import `getAuth` and `signInWithEmailAndPassword` from Firebase, which are essential for authentication processes.
2. **Initialization of Authentication**: `getAuth()` is called to initialize the authentication service from Firebase which provides the context for our operations.
3. **Creating the Login Function**: We use the `useCallback` hook to define our login function. This function is wrapped in a `useCallback` to ensure it only recomputes if `auth` changes. Inside, we use the `signInWithEmailAndPassword` function, passing the `auth` instance along with the provided email and password.
4. **Error Handling**: Our function contains a try-catch block to handle errors effectively. In the event of login failure, the error is logged, and then re-thrown, possibly to be caught by a parent component or error boundary for appropriate handling.
5. **Exporting the Hook**: The `login` method is returned wrapped in an object, making it easily accessible when the hook is used in other parts of the application.
## Conclusion
Integrating Firebase with React Hooks like `useCallback` offers a robust solution for managing user authentication in your React applications.

1,903,978 | Redes: TCP - Entendendo o Protocolo de Controle de Transmissão | Em um mundo cada vez mais conectado, onde a comunicação digital é essencial, os protocolos de rede... | 0 | 2024-06-28T10:51:43 | https://dev.to/iamthiago/redes-tcp-entendendo-o-protocolo-de-controle-de-transmissao-4e50 | Em um mundo cada vez mais conectado, onde a comunicação digital é essencial, os protocolos de rede desempenham um papel crucial. Entre os diversos protocolos que sustentam a internet, o TCP (Transmission Control Protocol ou Protocolo de Controle de Transmissão) se destaca por sua importância e abrangência. Neste artigo, vamos explorar o que é o TCP, como ele funciona e por que é fundamental para a comunicação na internet.
#### O que é o TCP?
O TCP é um protocolo de transporte da camada de rede, responsável por garantir a entrega confiável de dados entre dispositivos em uma rede. Ele é um dos principais protocolos utilizados na internet, juntamente com o UDP (User Datagram Protocol). Diferente do UDP, que não oferece garantias de entrega, o TCP se destaca por fornecer uma comunicação confiável e ordenada.
#### Como o TCP Funciona?
O TCP opera em um modelo de comunicação orientado à conexão. Antes que qualquer dado possa ser transmitido, uma conexão deve ser estabelecida entre o emissor e o receptor. Este processo de estabelecimento de conexão é conhecido como "three-way handshake" (aperto de mão triplo), que envolve três etapas:
1. **SYN (Synchronize)**: O cliente envia um segmento SYN para o servidor para iniciar a conexão.
2. **SYN-ACK (Synchronize-Acknowledge)**: O servidor responde com um segmento SYN-ACK, reconhecendo o pedido do cliente e sincronizando a sequência de números.
3. **ACK (Acknowledge)**: O cliente envia um segmento ACK ao servidor, confirmando a recepção do SYN-ACK e estabelecendo a conexão.
Uma vez estabelecida a conexão, os dados podem ser transmitidos de forma confiável. O TCP divide os dados em segmentos e garante que cada segmento chegue ao destino correto, utilizando números de sequência e confirmações de recebimento (ACKs). Se algum segmento se perder ou chegar corrompido, ele será retransmitido.
#### Principais Características do TCP
1. **Confiabilidade**: O TCP garante que os dados sejam entregues corretamente e na ordem correta. Se um segmento se perder, ele será retransmitido até que o receptor confirme sua recepção.
2. **Controle de Fluxo**: O TCP gerencia a quantidade de dados que podem ser enviados antes de receber uma confirmação, ajustando dinamicamente o fluxo de dados para evitar sobrecarga na rede.
3. **Controle de Congestionamento**: O TCP possui mecanismos para detectar e reagir à congestão na rede, ajustando a taxa de transmissão para evitar o congestionamento e melhorar o desempenho geral.
4. **Orientado à Conexão**: Antes da transmissão de dados, uma conexão deve ser estabelecida entre os dois pontos de comunicação, garantindo que ambos estejam prontos para a troca de informações.
#### Aplicações do TCP
O TCP é amplamente utilizado em diversas aplicações que requerem comunicação confiável, incluindo:
- **Web Browsing**: A navegação na web utiliza o protocolo HTTP/HTTPS, que é baseado em TCP.
- **Email**: Protocolos como SMTP, POP3 e IMAP utilizam TCP para garantir a entrega de mensagens de email.
- **Transferência de Arquivos**: Protocolos como FTP e SFTP dependem do TCP para transferir arquivos de forma confiável.
#### Conclusão
O TCP é um dos pilares fundamentais da internet moderna, garantindo a entrega confiável e ordenada de dados em uma vasta gama de aplicações. Seu papel na comunicação digital é essencial para a experiência do usuário, proporcionando uma rede robusta e eficiente.

1,903,976 | The Shift In Tech | Being a tech bro. or sis. and working a 9-to-5 job was something many of us took pride in during... | 0 | 2024-06-28T10:50:23 | https://dev.to/divine-ikechukwu/the-shift-in-tech-2c4k | programming, beginners |
Being a tech bro. or sis. and working a 9-to-5 job was something many of us took pride in during the COVID-19 period. Many of us made an impressive amount of money just pursuing our passion back then. But, I hate to say it, that era is fading. Some big companies are being forced to lay off their skilled workers simply because they no longer need them. You probably get the gist by now. Don’t get me wrong, I’m not saying tech itself is dying off. I’m only saying that certain jobs or skills are becoming less essential to learn.
With the growth in AI over recent years, tech is shifting, and you need to keep up. Why hire someone to do a ten-hour job when an AI can do it more efficiently in three seconds? This is the thinking driving the change I'm writing about.
For developers, you might have heard of Devlin, the first ever proclaimed AI programmer. It was quite popular earlier this year. While most developers panicked and a few dismissed it as just an idea, you should realize that with the current level of innovation and competition in AI, it's only a matter of time before we see something even better than that Devlin concept.
This isn't to scare any particular niche or job; it’s simply an awareness that tech is shifting! AI is coming for some of our jobs, whether we like it or not. It's changing not just the tech world but everything that relies on it. And we both know that almost everything nowadays depends on technology. Even business founders and owners are starting to realize the shift in technology. Previously, it was enough to have a good product online, make it easily accessible, and generate sales. Today, customers want more; they want to connect with you, not just the brand. That's why you see most CEOs like Elon Musk and Tony Elumelu on social media platforms like TikTok, X, and LinkedIn, talking about their businesses instead of leaving it all to the marketing team.
So, what can you do to stay relevant? Well, as a techie, this feeling shouldn’t be new to you. What do you do when a new framework comes out or when you’re troubleshooting a bug for hours? You start learning and digging again. In tech, knowledge itself fades; you have to keep updating it with new information. It’s a struggle. Trust me, I understand.
Another way is to start being creative. If you see a pattern in something that can be learned with the right rules, know that AI can replace you in that task. It’s only a question of when. Do things entirely differently, so that even if an AI can do it, it will be said that it cannot do it like you. For example, this very writing is different from any generated article you will ever come across because I wrote it as if it had my voice in it. This is exactly how I would have spoken to you if I were telling you these things.
Also, I just want to remind you: AI is your friend. The mistake many of us make is seeing it as a competitor. No! It’s a friend—an assistant friend, at that. We can choose to have it on our side. It’s an added advantage to our existing strengths, and we shouldn’t ignore that. If you’re into content writing, for example, don’t just generate text from ChatGPT like most people. Be creative, do your own writing, and maybe use AI only to check for errors and conduct research. Just don’t be lazy with AI.
In conclusion, if there’s anything I want you to take away from this short piece, it’s the awareness that the tech world is shifting, and you need to adapt. One way is to be creative with whatever you’re currently doing. Be adaptable like flowing water. Keep leveling up your skills to stay relevant. It’s easier to learn every day to keep up than to wake up and find that the world you’re living in is in the past.
Let's stop here for now. You can check out my next article where I will reveal the new currency in today's world. Trust me, you won't want to miss that.
So, what do you think? Do you agree with my perspective, or do you think otherwise? Let me know your thoughts in the comments section below. I want to learn too 😊

1,902,978 | CSS wordwrap: Because Sometimes One Line Just Isn't Enough! | Controlling how text wraps with CSS can be a headache. CSS offers a number of text wrapping options... | 0 | 2024-06-28T10:48:07 | https://dev.to/patrick_clancey/a-deep-dive-into-css-and-text-wrapping-5862 | css, ux, frontend |
Controlling how text wraps with CSS can be a headache. CSS offers a number of text wrapping options to keep your content readable and responsive. So your text doesn't break the page layout or look like it lost a fight with a blender.
## Introduction
Text wrapping is vital in web design for content readability and visual appeal across different devices and screen sizes. CSS provides properties like `overflow-wrap`, `word-break`, `text-wrap` and `hyphens` that allow developers to control text behavior at the edge of its container. This post explores the practical use of these properties to manage long strings, prevent overflow, and enhance user experience. These CSS rules are essential when dealing with unbreakable URLs, optimizing text readability and maintaining responsive designs.
## Wrapping vs Truncation
For the purposes of this post I'm only going to focus on text that needs to be visible to the user, hence it needs to wrap and ignore the truncation option entirely. Although, there is some overlap in the use-cases, text truncation has a more specific use-case and is specifically for hiding content over a specific length. So I'm just going to skip over it here!
## Text wrapping style options
Let's jump straight in and take a look at some styles we can use to prevent strings form overflowing their container.
{% codepen https://codepen.io/clanceyp/pen/MWdVBEG %}
## TLDR
Ok, I'm going to skip the boring bits and go straight to the summary. (For reference, the rather dry detail about each style follows further down the page.)
```css
/* use for headings */
.my-h1 {
hyphens: auto;
overflow-wrap: break-word;
text-wrap: balance;
}
/* use for general static copy */
.my-text-container {
hyphens: auto;
overflow-wrap: break-word;
}
/*
use specifically for breaking long strings or
on large/dynamic content containers which
may contain long strings
*/
.my-url-container,
.my-very-big-text-container,
.my-dynamic-text-container {
overflow-wrap: break-word;
}
```
As with most things CSS, there is more than one way to solve the problem. But which is the best? Let's look at three use-cases. Headings where long words might overflow on small devices, static content containers which could contain long strings like URLs, and containers that could either contain a lot of content or are repeatedly updated dynamically. Let's take these three in revers order. For contains that contain a lot of content, or are dynamically updated we can use `overflow-wrap: break-word` this will keep the content within the containers' boundaries. For short or static content (see below for detail about hyphens and performance) we can add `hyphens: auto` this will improve readability, but we still keep `overflow-wrap: break-word` which will ensure that long strings still wrap if the content is in a language that the browser doesn't know how to hyphenate or the long strings aren't words. And lastly for headings (e.g. H1) we'll keep `hyphens` and `overflow-wrap` and we'll also add `text-wrap: balance` this adds visual balance to the mix, so the header wraps nicely.
## The boring bit
Let's look at the styles in more detail
### hyphens: auto;
Using `hyphens: auto` in CSS allows for automatic, language-aware hyphenation of text, which can significantly enhance the readability and aesthetic of text blocks, particularly in responsive designs and narrow layouts.
#### hyphens, on the downside
This does more than just breaking long strings that don't fit in the container. You might still get text overflowing the container, for example a very long number won't be hyphenated so will still remain on one line. `hyphens: auto` has a performance overhead due to the processing required to determine hyphenation points, especially in dynamic or large text content. To mitigate the impact of this, particularly for containers with extensive or frequently changing text, I recommend only using `hyphens: auto` on specific elements that would benefit from it, don't just randomly add it here, there and everywhere!
### overflow-wrap: break-word;
This style ensures that long words or unbreakable strings (such as URLs) break and wrap onto the next line instead of overflowing their container.
#### overflow-wrap, on the downside
Arbitrary word breaks at any point, which can lead to awkward or hard-to-read text breaks, disrupting the natural flow of reading. A small performance overhead (although less than that of hyphens).
### word-wrap: break-word;
This is an alias for `overflow-wrap: break-word`, which is the standardized property name. Use `overflow-wrap: break-word` instead.
### word-wrap: break-all;
I have nothing good to say about `word-wrap: break-all`. I can't think of any use-case for it. Only consider using this if you have a specific issue that isn't fixed by any of the other options!
#### break-all, on the downside
It breaks words excessively at any character, leading to awkward and very hard-to-read text at all widths.
## Balancing text-wrapping
The style `text-wrap: balance` does NOT break strings. This is shorthand property which controls how text inside an element is wrapped, it's not standard (yet) but has solid support in all major browser vendors. I use this on main header elements (e.g. h1) to visually balance the content and make it more aesthetically pleasing. This is part of the [css-text-4 text-wrapping proposal](https://www.w3.org/TR/css-text-4/#text-wrapping)
### text-wrap balance on the downside
I haven't seen any detailed performance metrics so I might be making too much of the potential performance impact. But nonetheless, I would only use this on specific static elements like headers. I wouldn't use this on large content blocks or anything that's repeatedly updated dynamically.

This is more of an Object Oriented Programming interview question rather than a Selenium WebDriver question.
First of all, there is absolutely **no problem** with a browser driver object being referenced by RemoteWebDriver instance variable. There will never be any problem with the automation testing framework script, until and unless Selenium decides to deprecate RemoteWebDriver (very unlikely).
Now let's quickly see the Selenium WebDriver hierarchy.
**_SearchContext_** interface : It has 2 methods - findElement(By locator) and findElements(By locator).
**_WebDriver_** interface : It extends SearchContext interface. So it has to override both the SearchContext methods. Along with that, it provides its own abstract methods.
**_WebElement_** interface : It extends SearchContext interface. So it automatically overrides both of its parent interface's methods. Along with that, it provides its own abstract methods.
**RemoteWebDriver** class : It implements WebDriver interface. So it overrides all the methods of WebDriver and SearchContext interfaces.
### RemoteWebDriver : the 1st Concrete class in WebDriver API hierarchy :
💡
> A concrete class is a class in which, all methods, including overridden and its own methods, are implemented.
> All methods from its parent and grandparent interfaces are implemented in RemoteWebDriver class. This is the concept of Inheritance in Object Oriented Programming. RemoteWebDriver and subsequent child classes such as ChromeDriver, EdgeDriver etc. are essentially inheriting properties of WebDriver. _The properties are declared in WebDriver interface. How these properties should work are defined in RemoteWebDriver class_.
### Using RemoteWebDriver instead of WebDriver :
The way we use the WebDriver API in our automation testing framework, there is no fundamental difference in WebDriver and RemoteWebDriver functionality-wise.
```
RemoteWebDriver driver1 = new ChomeDriver();
driver1.get("https://google.com");
//or,
WebDriver driver2 = new ChromeDriver();
driver2.get("https://google.com");
```
Here, both driver1 and driver2 will have same methods available to them. It won't affect any functionalities within the framework.
### Why we don't write RemoteWebDriver = new ChromeDriver() :
According to object oriented programming, we should,
> "code to interfaces"
That means, we should be able to maintain abstraction in our code as much as we can. Even though there is nothing wrong with writing RemoteWebDriver = new ChromeDriver(), we are exposing the implemented class here, rather than hiding it.
For better readability, we write WebDriver driver = new ChromeDriver(). We are concerned about what a method does, rather than how it does it. This level of abstraction can be achieved by creating driver object referenced by instance of the interface.

JavaScript is an essential technology for modern web development, powering dynamic and interactive web applications. However, as applications become more complex, optimizing JavaScript performance becomes crucial to ensure a smooth and responsive user experience. In this guide, we will explore advanced <b><a href="https://www.addwebsolution.com/hire-javascript-developer">hire JavaScript developers</a></b> performance optimization techniques that can help you build efficient and high-performing web applications. Whether you're a seasoned developer or just starting, these strategies will empower you to create faster and more efficient code.
<b><h2>Understanding JavaScript Performance</h2></b>
<b>Execution Time:</b> The time it takes for the JavaScript code to execute.
<b>Memory Usage:</b> The amount of memory the JavaScript code consumes.
<b>Network Latency:</b> The time it takes to load JavaScript files from the server.
<b>DOM Manipulation:</b> The impact of manipulating the Document Object Model (DOM) on performance.
By addressing these factors, you can significantly improve the performance of your JavaScript code and provide a better user experience.
<b><h3>1. Minimize DOM Manipulation</h3></b>
DOM manipulation is one of the most expensive operations in JavaScript, and excessive manipulation can lead to performance bottlenecks. To optimize DOM manipulation:
<b>Batch DOM Updates:</b> Instead of making multiple changes to the DOM, batch them together to minimize reflows and repaints.
<b>Use Document Fragments:</b> When adding multiple elements to the DOM, use `document.createDocumentFragment()` to create a fragment and append all elements to it before adding it to the DOM.
<b>Avoid Layout Thrashing:</b> Layout thrashing occurs when JavaScript reads from and writes to the DOM repeatedly, causing multiple reflows. To avoid this, separate read and write operations.
<b><h3>Example: Batch DOM Updates</h3></b>
```
// Inefficient way
const list = document.getElementById('list');
for (let i = 0; i < 100; i++) {
const listItem = document.createElement('li');
listItem.textContent = `Item ${i}`;
list.appendChild(listItem);
}
// Efficient way
const listFragment = document.createDocumentFragment();
for (let i = 0; i < 100; i++) {
const listItem = document.createElement('li');
listItem.textContent = `Item ${i}`;
listFragment.appendChild(listItem);
}
list.appendChild(listFragment);
```
<b><h2>2. Optimize JavaScript Execution</h2></b>
Optimizing the execution of your JavaScript code can lead to significant performance improvements. Some techniques to achieve this include:
<b>Use Efficient Data Structures:</b> Choose the right data structures for your tasks. For example, use arrays for ordered collections and objects for key-value pairs.
<b>Avoid Using `eval()`:</b> The `eval()` function can introduce security vulnerabilities and performance issues. Avoid using it and consider alternative methods.
<b>Minimize Function Calls:</b> Reduce the number of function calls in your code, especially within loops, to improve performance.
<b><h3>Example: Efficient Data Structures</h3></b>
```
// Inefficient way
const dataArray = [];
for (let i = 0; i < 10000; i++) {
dataArray.push({ id: i, value: `Item ${i}` });
}
const foundItem = dataArray.find(item => item.id === 5000);
// Efficient way
const dataObject = {};
for (let i = 0; i < 10000; i++) {
dataObject[i] = `Item ${i}`;
}
const foundValue = dataObject[5000];
```
<b><h2>3. Asynchronous Programming
</h2></b>
Asynchronous programming allows you to perform tasks without blocking the main thread, improving the responsiveness of your application. Some common asynchronous techniques include:
<b>Promises:</b> Promises provide a way to handle asynchronous operations in a more readable and maintainable manner.
<b>Async/Await:</b> The `async` and `await` keywords simplify working with promises, making asynchronous code look more like synchronous code.
<b>Web Workers:</b> Web Workers allow you to run JavaScript code in the background, separate from the main execution thread.
<b><h3>Example: Using Async/Await</h3></b>
```
// Using Promises
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => {
console.log(data);
})
.catch(error => {
console.error('Error:', error);
});
// Using Async/Await
async function fetchData() {
try {
const response = await fetch('https://api.example.com/data');
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Error:', error);
}
}
fetchData();
```
<b><h2>4. Reduce JavaScript Payload</h2></b>
Reducing the size of your JavaScript files can lead to faster load times and improved performance. Some strategies to achieve this include:
<b>Minification:</b> Minify your JavaScript files to remove unnecessary characters, such as whitespace and comments.
<b>Code Splitting:</b> Split your JavaScript code into smaller chunks that can be loaded on demand, reducing the initial load time.
<b>Tree Shaking:</b> Remove unused code from your JavaScript bundles to reduce their size.
<b><h3>Example: Code Splitting with Webpack</h3></b>
```
// webpack.config.js
module.exports = {
entry: {
main: './src/index.js',
vendor: './src/vendor.js'
},
output: {
filename: '[name].bundle.js',
path: __dirname + '/dist'
},
optimization: {
splitChunks: {
chunks: 'all'
}
}
};
```
<b><h2>5. Optimize Network Requests</h2></b>
Network requests can significantly impact the performance of your web application. To optimize network requests:
<b>Use a Content Delivery Network (CDN):</b> Host your JavaScript files on a CDN to reduce latency and improve load times.
<b>Lazy Loading:</b> Load JavaScript files only when they are needed, reducing the initial load time.
<b>Caching:</b> Utilize browser caching to store JavaScript files locally and avoid repeated downloads.
<b><h3>Example: Lazy Loading JavaScript</h3></b>
```
// HTML
<button id="loadScript">Load Script</button>
<div id="content"></div>
// JavaScript
document.getElementById('loadScript').addEventListener('click', () => {
const script = document.createElement('script');
script.src = 'path/to/your/script.js';
script.onload = () => {
// Script loaded and executed
initializeContent();
};
document.body.appendChild(script);
});
```
<b><h2>6. Memory Management</h2></b>
Efficient memory management is crucial for maintaining the performance of your web application. Some tips for managing memory in JavaScript include:
- **Avoid Memory Leaks**: Ensure that you do not create memory leaks by properly cleaning up resources and event listeners.
- **Use Weak References**: Use `WeakMap` and `WeakSet` to hold references to objects that can be garbage collected if there are no other references to them.
- **Profile Memory Usage**: Use browser developer tools to profile and analyze memory usage, identifying areas for improvement.
<b></h3>Example: Avoiding Memory Leaks</h3></b>
```
// Inefficient way
function createEventListeners() {
const element = document.getElementById('myElement');
element.addEventListener('click', () => {
console.log('Element clicked');
});
}
createEventListeners();
// Efficient way
function createEventListeners() {
const element = document.getElementById('myElement');
function handleClick() {
console.log('Element clicked');
}
element.addEventListener('click', handleClick);
// Clean up the event listener when it's no longer needed
return () => element.removeEventListener('click', handleClick);
}
const removeEventListener = createEventListeners();
// Call removeEventListener when needed
```
<b></h2>7. Use Efficient Algorithms and Data Structures</h2></b>
Choosing the right algorithms and data structures can have a significant impact on the performance of your JavaScript code. Some best practices include:
<b>Use Hash Tables for Fast Lookups:</b> Use objects or `Map` for fast key-value lookups.
<b>Avoid Nested Loops:</b> Minimize the use of nested loops, as they can lead to performance bottlenecks. Optimize your algorithms to reduce their time complexity.
<b>Use Binary Search for Sorted Data:</b> When working with sorted data, use binary search to achieve faster search times.
<b></h3>Example: Using Binary Search</h3></b>
```
function binarySearch(arr, target) {
let left = 0;
let right = arr.length - 1;
while (left <= right) {
const mid = Math.floor((left + right) / 2);
if (arr[mid] === target) {
return mid;
} else if (arr[mid] < target) {
left = mid + 1;
} else {
right = mid - 1;
}
}
return -1;
}
const sortedArray = [1, 3, 5, 7, 9, 11];
const index = binarySearch(sortedArray, 7);
console.log(index); // Output: 3
```
<b></h3>8. Optimize Rendering Performance</h3></b>
Rendering performance is crucial for ensuring a smooth user experience. To optimize rendering performance:
<b>Use CSS for Animations:</b> Whenever possible, use CSS for animations instead of JavaScript. CSS animations are often more performant because they can be hardware-accelerated.
<b>Minimize Repaints and Reflows:</b> Reduce the number of repaints and reflows by avoiding unnecessary DOM manipulations and using efficient layout strategies.
<b>Debounce and Throttle Events:</b> Use debounce and throttle techniques

programming
As a self-taught front-end developer, I ventured into the world of web development out of curiosity to understand how web applications work. During my learning journey, I discovered that there are numerous options available for front-end technologies, which can be quite overwhelming. With new technologies being constantly introduced, it can be difficult to decide where to start. Today, I'd like to discuss two ideal front-end technologies that beginners should focus on to avoid feeling overwhelmed: ReactJS and Vue.js.
ReactJS vs. Vue.js:
Performance:
Both ReactJS and Vue.js offer excellent performance but achieve this through different mechanisms. ReactJS uses a virtual DOM to efficiently update and render only the necessary parts of the UI, minimizing direct interactions with the actual DOM. Vue.js, on the other hand, uses a reactive data binding system that ensures efficient DOM updates, automatically reflecting changes in the UI.
Learning Curve and Syntax:
ReactJS uses JSX, which combines JavaScript and HTML-like syntax. While powerful, it requires a solid understanding of JavaScript ES6+ and can present a steeper learning curve for beginners. Vue.js is often praised for its approachable syntax and simplicity, making it easier for beginners to pick up and start building applications quickly.
Ecosystem and Community:
ReactJS boasts a vast ecosystem with numerous libraries and tools that extend its capabilities. It also has a large and active community, providing extensive resources, tutorials, and support. Vue.js, while having a smaller ecosystem, still offers robust community support and excellent, beginner-friendly documentation.
Flexibility and Use Cases:
Vue.js is designed to be incrementally adoptable, making it a flexible choice for adding to existing projects without extensive rewriting. ReactJS, known for its component-based architecture, is often used to build entire applications from scratch and is suitable for a wide range of applications, from small widgets to large enterprise-level apps.
Job Market:
ReactJS has a larger job market compared to Vue.js, making it a valuable skill for aspiring developers. However, Vue.js is also growing in popularity and offers opportunities, particularly in startups and smaller projects.
My Journey with ReactJS and HNG
Why I Chose ReactJS
I have explored both ReactJS and Vue.js and understand the benefits of both. However, ReactJS edges above Vue.js and is the popular choice among experienced developers. This is why I began studying it using the React course provided by Meta. Even top organizations, like HNG, primarily use ReactJS.
How I Feel About ReactJS:
React has been a game-changer in the frontend landscape. Its component-based architecture simplifies the development process, and the extensive ecosystem means there's a library or tool for almost any need.
What is HNG?
HNG is one of the top tech organizations in Africa, offering pathways to upskill and become a valuable contributor in the tech space. By joining the HNG internship program, you can gain valuable skills, improve your knowledge, and build a network of like-minded individuals.
HNG's programs are designed for intermediate to advanced learners aiming to advance their careers and secure jobs in top international companies. To maximize your experience, consider subscribing to HNG Premium. This subscription provides access to remote job offers, tech talks, coding gigs, annual meetups, networking opportunities, and engaging discussions.
What I Expect to Do in HNG
At HNG, I expect to leverage ReactJS to build scalable and maintainable web applications. My focus will be on creating reusable components, optimizing performance, and ensuring a seamless user experience.
Conclusion
Choosing the right front-end technology as a beginner can set the tone for your learning journey. Both ReactJS and Vue.js offer robust ecosystems, strong community support, and valuable learning resources. Starting with either technology helps you build a solid foundation in web development without feeling overwhelmed. Remember, start small, stay consistent, and enjoy the process.

Welcome to an exciting journey into the world of real-time data with HarperDB and Node.js! Imagine having an IoT dashboard that updates in real-time, giving instant insights into your data. Sounds intriguing, right? That's precisely what you'll build in this tutorial.
HarperDB is a powerful tool that combines a distributed database, cache, application, and streaming system into a single process. This unique combination allows for high performance and simplicity at scale, making it an excellent choice for real-time applications. In this project, you'll leverage HarperDB's capabilities to create a real-time IoT dashboard.
By the end of this tutorial, you'll have a fully functional dashboard that can visualize data from IoT devices in real-time.
You'll learn how to:
Set up and configure HarperDB
Simulate an IoT device sending data
Build a Node.js server to handle real-time data
Create a dynamic frontend to display data
Whether you're a seasoned developer or just getting started, this tutorial is designed to be hands-on and straightforward. Each step will guide you through the process, ensuring you understand how everything fits together. Ready to dive in and start building? Let's get started!
## Project Setup
Start by setting up HarperDB and then create the necessary project structure. Follow these steps to get everything in place.
**1. Installing and Configuring HarperDB**
First, you'll need to install HarperDB. If you haven't already, head to the HarperDB website for the installation instructions tailored to your operating system.
After installing HarperDB, you need to start the HarperDB server. Open your terminal and run the following command:
```bash
harperdb run
```
You should see a message indicating that HarperDB is up and running. By default, HarperDB runs on port 9925. You can access the HarperDB Studio at http://localhost:9925 to manage your database.
**2. Setting Up the Project Directory and Necessary Files**
Now, set up the project directory. Open your terminal and navigate to your preferred workspace. Create a new directory for our project and navigate into it:
```bash
mkdir real-time-iot-dashboard
cd real-time-iot-dashboard
```
Next, initialize a new Node.js project:
```bash
npm init -y
```
This command creates a package.json file with the default settings. Now, install the required dependencies. You’ll need Express for our server, Axios for making HTTP requests, and WebSocket for real-time communication:
```bash
npm install express axios ws
```
With the dependencies installed, you'll need to create the necessary files and directories. Run the following commands:
```bash
mkdir public
touch server.js public/index.html
```
Here’s a quick overview of what each file will do:
server.js: This will be the main server file, handling HTTP and WebSocket connections.
public/index.html: This will be the frontend file, displaying the real-time data.
**3. Configuring HarperDB**
Before moving on, you must set up a table in HarperDB to store the IoT data.
Create a file called `schema.graphql` in your project directory, then paste the following code:
```json
type SensorData @table @export {
id: ID @primaryKey
timestamp: String
temperature: String
humidity: String
}
```
In a separate terminal window, run the following command to have HarperDB monitor the application directory:
```bash
harperdb dev .
```
You can learn more about creating tables in the Applications section.
## Simulating an IoT Device
With the project setup complete, it's time to simulate an IoT device sending data to HarperDB. Create a Node.js script that generates random sensor data and sends it to the HarperDB instance. Follow these steps to get started.
**1. Creating the Node.js Script**
First, create a new file in the project directory called simulate_device.js:
```bash
touch simulate_device.js
```
Open this file in your preferred code editor and start by requiring the necessary modules. Use Axios to send HTTP requests to HarperDB.
```javascript
const axios = require('axios');
const { v4: uuidv4 } = require('uuid');
```
The uuid library will generate unique IDs for the sensor data. Install this library by running:
```javascript
npm install uuid
```
**2. Generating Random Sensor Data**
Next, create a function to generate random sensor data. Assume the IoT device measures temperature and humidity.
```javascript
function generateSensorData() {
return {
id: uuidv4(),
timestamp: new Date().toISOString(),
temperature: (Math.random() * 40).toFixed(2), // Random temperature between 0 and 40
humidity: (Math.random() * 100).toFixed(2) // Random humidity between 0 and 100
};
}
```
**3. Sending Data to HarperDB**
Now, create a function to send the generated sensor data to HarperDB using the REST API.
```javascript
async function sendDataToHarperDB(data) {
const config = {
method: 'post',
url: 'http://localhost:9926/SensorData',
headers: {
'Content-Type': 'application/json'
},
data: JSON.stringify(data)
};
try {
const response = await axios(config);
console.log('Data sent successfully:', response.data);
} catch (error) {
console.error('Error sending data:', error);
}
}
```
**4. Automating Data Generation and Sending**
Finally, create a loop to generate and send data at regular intervals. For instance, send data every 5 seconds.
```javascript
setInterval(() => {
const data = generateSensorData();
sendDataToHarperDB(data);
}, 5000);
```
The complete `simulate_device.js` script should look like this:
```javascript
const axios = require('axios');
const { v4: uuidv4 } = require('uuid');
function generateSensorData() {
return {
id: uuidv4(),
timestamp: new Date().toISOString(),
temperature: (Math.random() * 40).toFixed(2),
humidity: (Math.random() * 100).toFixed(2)
};
}
async function sendDataToHarperDB(data) {
const config = {
method: 'post',
url: 'http://localhost:9926/SensorData',
headers: {
'Content-Type': 'application/json'
},
data: JSON.stringify(data)
};
try {
const response = await axios(config);
console.log('Data sent successfully:', response.data);
} catch (error) {
console.error('Error sending data:', error);
}
}
setInterval(() => {
const data = generateSensorData();
sendDataToHarperDB(data);
}, 5000);
```
Run the script using the following command:
```bash
node simulate_device.js
```
The script will start generating random sensor data and sending it to HarperDB every 5 seconds. This setup simulates an IoT device and provides data for the real-time dashboard.
In the next section, you'll build the real-time data ingestion setup, ensuring the IoT data flows smoothly into the dashboard.
## Real-Time Data Ingestion
Now that your IoT device simulation sends data to HarperDB, it's time to set up real-time data ingestion. This setup will allow the frontend to receive and display data as soon as it's available. Follow these steps to create a seamless flow of data from HarperDB to the dashboard.
**1. Setting Up the Node.js Server**
First, you'll create a Node.js server to handle real-time data communication. This server will use WebSocket to push updates to the frontend.
Open the `server.js` file and start by requiring the necessary modules:
```javascript
const express = require('express');
const http = require('http');
const WebSocket = require('ws');
const axios = require('axios');
```
Next, set up the basic Express server and HTTP server:
```javascript
const app = express();
const server = http.createServer(app);
const wss = new WebSocket.Server({ server });
// Serve static files from the 'public' directory
app.use(express.static('public'));
// Serve index.html at the root endpoint
app.get('/', (req, res) => {
res.sendFile(__dirname + '/public/index.html');
});
// Start the server on port 3000
server.listen(3000, () => {
console.log('Server is running on http://localhost:3000');
});
```
**2. Handling WebSocket Connections**
Set up the WebSocket server to handle connections and send real-time data to connected clients:
```javascript
wss.on('connection', (ws) => {
console.log('Client connected');
ws.on('close', () => {
console.log('Client disconnected');
});
});
```
**3. Fetching Data from HarperDB**
To fetch data from HarperDB, create a function that retrieves the latest sensor data. Use this function to periodically check HarperDB for new data and send updates to the frontend:
```javascript
async function fetchDataAndUpdateClients() {
const config = {
method: 'post',
url: 'http://localhost:9925', // HarperDB endpoint
headers: {
'Content-Type': 'application/json'
},
data: JSON.stringify({
operation: 'sql',
sql: 'SELECT * FROM data.SensorData ORDER BY timestamp DESC LIMIT 1'
})
};
try {
const response = await axios(config);
const latestData = response.data;
// Check if the response data is an array (expected format)
if (Array.isArray(latestData)) {
// Broadcast latest data to all connected clients
wss.clients.forEach((client) => {
if (client.readyState === WebSocket.OPEN) {
client.send(JSON.stringify(latestData));
}
});
} else {
console.error('Unexpected data format:', latestData);
}
} catch (error) {
console.error('Error fetching data:', error);
}
}
// Periodically fetch data and update clients every 5 seconds
setInterval(fetchDataAndUpdateClients, 5000);
```
This function queries HarperDB for the latest sensor data and sends it to all connected WebSocket clients every 5 seconds.
If you go to http://localhost:9925/SensorData you should see something like this:
**4. Setting Up the Frontend to Receive Data**
Finally, configure the frontend to connect to the WebSocket server and display the received data. Open the `public/index.html` file and add the following code:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Real-Time IoT Dashboard</title>
</head>
<body>
<h1>Real-Time IoT Dashboard</h1>
<div id="dataContainer">
<p>Waiting for data...</p>
</div>
<script>
const dataContainer = document.getElementById('dataContainer');
const ws = new WebSocket('ws://localhost:3000');
ws.onmessage = (event) => {
const data = JSON.parse(event.data);
if (Array.isArray(data)) {
dataContainer.innerHTML = ''; // Clear previous data
data.forEach(sensorData => {
const { id, timestamp, temperature, humidity } = sensorData;
const dataDiv = document.createElement('div');
dataDiv.classList.add('data-item');
dataDiv.innerHTML = `
<p>ID: ${id}</p>
<p>Timestamp: ${timestamp}</p>
<p>Temperature: ${temperature} °C</p>
<p>Humidity: ${humidity} %</p>
<hr>
`;
dataContainer.appendChild(dataDiv);
});
} else {
console.error('Received unexpected data format:', data);
// Handle single data object case, if needed
const { id } = data;
const dataDiv = document.createElement('div');
dataDiv.classList.add('data-item');
dataDiv.innerHTML = `
<p>ID: ${id}</p>
<p>Unexpected data format, check console for details.</p>
`;
dataContainer.appendChild(dataDiv);
}
};
ws.onopen = () => {
console.log('WebSocket connection established.');
};
ws.onclose = () => {
console.log('WebSocket connection closed.');
};
</script>
</body>
</html>
```
This code establishes a WebSocket connection to the server and updates the page with the latest sensor data.
At this point the application should look like this:
## Building the Dashboard
Now that you've set up real-time data ingestion, it's time to build a polished and interactive dashboard to visualize the IoT data. Follow these steps to enhance the user interface and create dynamic charts.
**1. Setting Up Chart.js**
To create beautiful charts, use Chart.js. First, add the Chart.js library to your project. Include the following script tag in the <head> section of your `public/index.html` file:
```html
<head>
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<script src="https://cdn.jsdelivr.net/npm/chartjs-adapter-date-fns@3.0.0"></script>
</head>
```
**2. Creating the HTML Structure**
Modify the HTML structure to include a canvas element for the chart. Update the `public/index.html` file:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Real-Time IoT Dashboard</title>
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<script src="https://cdn.jsdelivr.net/npm/chartjs-adapter-date-fns@3.0.0"></script>
<link rel="stylesheet" href="styles.css">
<script>
console.log("Chart.js loaded:", Chart); // Check if Chart.js is loaded
</script>
</head>
<body>
<h1>Real-Time IoT Dashboard</h1>
<div id="dataContainer">
<p>Waiting for data...</p>
</div>
<canvas id="myChart" width="400" height="200"></canvas>
<script>
const dataContainer = document.getElementById('dataContainer');
const ctx = document.getElementById('myChart').getContext('2d');
const ws = new WebSocket('ws://localhost:3000');
let chart;
ws.onmessage = (event) => {
const data = JSON.parse(event.data);
if (Array.isArray(data)) {
dataContainer.innerHTML = ''; // Clear previous data
data.forEach(sensorData => {
const { id, timestamp, temperature, humidity } = sensorData;
const dataDiv = document.createElement('div');
dataDiv.classList.add('data-item');
dataDiv.innerHTML = `
<p>ID: ${id}</p>
<p>Timestamp: ${timestamp}</p>
<p>Temperature: ${temperature} °C</p>
<p>Humidity: ${humidity} %</p>
<hr>
`;
dataContainer.appendChild(dataDiv);
updateChart(sensorData);
});
} else {
console.error('Received unexpected data format:', data);
// Handle single data object case, if needed
const { id } = data;
const dataDiv = document.createElement('div');
dataDiv.classList.add('data-item');
dataDiv.innerHTML = `
<p>ID: ${id}</p>
<p>Unexpected data format, check console for details.</p>
`;
dataContainer.appendChild(dataDiv);
}
};
ws.onopen = () => {
console.log('WebSocket connection established.');
};
ws.onclose = () => {
console.log('WebSocket connection closed.');
};
function createChart(data) {
chart = new Chart(ctx, {
type: 'line',
data: {
labels: [data.timestamp],
datasets: [
{
label: 'Temperature (°C)',
data: [data.temperature],
borderColor: 'rgba(255, 99, 132, 1)',
borderWidth: 1,
fill: false
},
{
label: 'Humidity (%)',
data: [data.humidity],
borderColor: 'rgba(54, 162, 235, 1)',
borderWidth: 1,
fill: false
}
]
},
options: {
scales: {
x: {
type: 'time',
time: {
unit: 'minute'
}
},
y: {
beginAtZero: true
}
}
}
});
}
function updateChart(data) {
if (chart) {
chart.destroy(); // Destroy the existing chart instance
}
createChart(data);
}
</script>
</body>
</html>
```
**3. Initializing the Chart**
The `createChart` function initializes the chart with the first data point received. It sets up two datasets, one for temperature and one for humidity. The `updateChart` function updates the chart with new data points as they arrive.
**4. Updating the Chart**
Each time new data is received through the WebSocket, the `updateChart` function adds the latest data to the chart and updates the display.
**5. Styling the Dashboard**
Add some basic CSS to improve the dashboard's appearance. Create a `public/styles.css` file and include it in the HTML file:
```css
body {
font-family: Arial, sans-serif;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
height: 100vh;
margin: 0;
}
h1 {
margin-bottom: 20px;
}
#data {
margin-bottom: 20px;
text-align: center;
}
canvas {
max-width: 100%;
height: auto;
}
```
Ensure your dashboard is optimized for mobile devices by implementing responsive design principles. Adjust layout and styling to provide a seamless user experience across different screen sizes.
```css
/* Example CSS for responsive design */
@media (max-width: 768px) {
body {
font-size: 14px;
}
/* Adjust other styles as needed */
}
```
Look at this thing of beauty!

* [Conclusion.](#conclusion)
##Introduction to Mongoose
Mongoose is an ODM (Object Data Modeling) library designed to streamline the interaction between your MongoDB database and Node.js applications.It is designed to work with asynchronous environments and offers a powerful set of features that simplify data manipulation and validation.
##Connecting to the database
Before diving into Mongoose, you need to establish a connection to your MongoDB database. Here’s a step-by-step guide to get you started:
###1.Installing Mongoose
`npm install mongoose`
###2. Importing Mongoose and creating a connection file
Create a file called _connect.js_ and place the connection logic there. This function returns a promise, which allows you to handle the connection success or failure in your main file.:
```
//connect.js
const mongoose = require('mongoose')
const connectDB = (url) => {
return mongoose.connect(url)
}
module.exports = connectDB
```
###3. Use the Connection in Your Main File:
In your main application file for example _app.js_, import and use the connection logic:
```
//app.js
require('dotenv').config();
const express = require('express');
const app = express();
// connectdb
const connectDB = require("./db/connect"); //Add the path to the connection logic file.
// Get the MongoDB connection string from environment variables
const MONGODB_STRING = process.env.MONGODB_STRING;
app.get("/", (req, res) => {
res.send("Hello Heroku app");
});
const port = process.env.PORT || 4040;
// Function to start the server
const start = async () => {
try {
// Connect to the database. Pass the MongoDB String as an arguement of the connectDB function.
await connectDB(MONGODB_STRING)
app.listen(port, () =>
console.log(`Connected to the database and listening on port ${port}...`)
);
} catch (error) {
console.log(error);
}
};
start();
```
###Explanation
- Environment Variables: Use dotenv to load _MONGODB_STRING_ and
_PORT_.
- Database Connection: connectDB in _db/connect.js_ in my case returns
a promise for
the database connection.
- Async/Await: Use async/await in app.js to ensure the server starts
only after a successful database connection.
- Error Handling: Handle connection errors with a try/catch block.
##Creating Models and Schemas
In Mongoose, models and schemas are fundamental for defining and interacting with data in MongoDB.
- **Schema**: Defines the structure of your data. It specifies the shape that each document (instance) will have in the database. Think of it as a blueprint.
- **Model**: Once you have a schema, you compile it into a model. A model is a JavaScript class that represents a collection in MongoDB. It is responsible for creating and reading documents from the database.
- **Document**: An instance of a model is called a document. Each document is a record in your MongoDB collection, based on the schema you defined.
Create a file called _job.js_ and place to place your logic there.
```
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const JobSchema = new Schema(
{
company: {
type: String,
required: [true, "Please the field can't be empty"],
},
position: {
type: String,
required: [true, "Please the field can't be empty"],
},
status: {
type: String,
required: [true, "Please the field can't be empty"],
enum: ["interview", "declined", "pending", "accepted"],
default: "pending",
},
},
{ timestamps: true }
);
const JobModel = mongoose.model("Job", JobSchema);
module.exports = JobModel;
```
###Explanation
- Schema Definition: **JobSchema ** defines fields _company_, _position_, _status _ and their types. It includes validations (required, enum) and a default value _default_.
Model Creation: **JobModel ** is created using mongoose.model(), linking Job as the collection name in MongoDB.
##Using Your Model in Controller Functions
In an Express application using Mongoose, it's common to separate your model definitions from your controller logic. This promotes modularity and improves code organization. So you can create a file and place your logic there for controller functions.
- **Controller Functions**: These functions _getAllJobs_, _createJob_, _getJob_, _updateJob_, _deleteJob_ handle CRUD operations for jobs. They interact with the imported (JobModel) to perform database operations based on HTTP requests.
- You will export this controller function and map them to the routes.
```
const JobModel = require("../models/Job");
const { StatusCodes } = require("http-status-codes");
const { BadRequestError, NotFoundError } = require("../errors/bad-request");
const getAllJobs = async (req, res) => {
const jobs = await JobModel.find({ createdBy: req.user.userId });
res.status(StatusCodes.CREATED).json({ jobs });
};
const createJobs = async (req, res) => {
req.body.createdBy = req.user.userId;
const jobs = await JobModel.create(req.body);
res.status(StatusCodes.CREATED).json({ jobs });
};
const getJob = async (req, res) => {
const {
user: { userId },
params: { id: job_id },
} = req;
const job = await JobModel.findOne({ _id: job_id, createdBy: userId });
if (!job) {
throw new NotFoundError(`No job with id: ${job_id}`);
}
res.status(StatusCodes.OK).json({ job });
};
const updateJob = async (req, res) => {
const {
body: { company, position },
params: { id: job_id },
user: { userId },
} = req;
if (company === "" || position === "") {
throw new BadRequestError("company and position cannot be found");
}
const job = await JobModel.findByIdAndUpdate(
{ _id: job_id, createdBy: userId },
req.body,
{ new: true, runValidators: true }
);
res.status(StatusCodes.OK).json({ job });
};
const deleteJob = async (req, res) => {
const {
params: { id: job_id },
user: { userId },
} = req;
const job = await JobModel.findByIdAndDelete({
_id: job_id,
createdBy: userId,
});
if (!job) {
throw new NotFoundError(`No user with id: ${job_id}`);
}
res.status(StatusCodes.OK).json({ msg: "Job deleted successfully" });
};
module.exports = {
getAllJobs,
createJobs,
getJob,
updateJob,
deleteJob,
};
```
###Import Controller Functions:
Import controller functions _getAllJobs_, _createJob_, _getJob_, _updateJob_, _deleteJob_ from the path your controller function login is located.
- Mapping Routes: Each HTTP method _GET_, _POST_, _PUT_, _DELETE_ is mapped to its corresponding controller function _getAllJobs_, _createJob_, _getJob_, _updateJob_, _deleteJob_.
```
const express = require('express');
const router = express.Router();
const auth = require("../middleware/authentication");
const {
getAllJobs,
getJob,
createJobs,
updateJob,
deleteJob,
} = require("../controllers/jobs");
router.use(auth);
router.route('/').get(getAllJobs).post(createJobs);
router.route('/:id').get(getJob).patch(updateJob).delete(deleteJob);
module.exports = router;
```
###Importing your router in your main file.
In an Express application, routers are used to organize and handle different sets of routes. Here is how you integrate a router into your main application file.
###Import the router in your main file (app.js)
`const jobRoutes = require("./routes/jobs");`
###Applying Router Middleware in your main file (app.js)
```
//app.js
require('dotenv').config();
const express = require('express');
const app = express();
//imported router
const jobRoutes = require("./routes/jobs");
// connectdb
const connectDB = require("./db/connect"); //Add the path to the connection logic file.
// Get the MongoDB connection string from environment variables
const MONGODB_STRING = process.env.MONGODB_STRING;
app.get("/", (req, res) => {
res.send("Hello Heroku app");
});
const port = process.env.PORT || 4040;
// Function to start the server
const start = async () => {
try {
// Connect to the database. Pass the MongoDB String as an arguement of the connectDB function.
await connectDB(MONGODB_STRING)
app.listen(port, () =>
console.log(`Connected to the database and listening on port ${port}...`)
);
} catch (error) {
console.log(error);
}
};
start();
```

1,903,960 | Comparing React.js and Svelte: A Deep Dive into Frontend Technologies | In the world of web and app development the choice of framework can significantly impact the... | 0 | 2024-06-28T10:35:30 | https://dev.to/reverd_ssounds_f3fff44526/comparing-reactjs-and-svelte-a-deep-dive-into-frontend-technologies-2dp4 | In the world of web and app development the choice of framework can significantly impact the efficiency and performance of your projects.
While React.js has been a dominant force in the industry for years, Svelte has emerged as a compelling alternative with it's unique approach. In this article, I'll be comparing React.js and Svelte frameworks, exploring their features, strengths, and what sets them apart. Here we go =>
**REACT.js: The Component-Based Frame-work**
React.js was developed by Facebook and has revolutionized frontend development with its component-based architecture and virtual DOM. It allows developers to build complex UIs by breaking them down into reusable components thereby making code management and maintenance more manageable.
**React.js Key Features** =>
- Component-Based Architecture: this promotes the creation of reusable components, improving code organization and reusability and from my experience this approach has been efficient in terms of organization of one's code.
- Virtual DOM: React.js's' virtual DOM efficiently updates the UI, minimizing direct manipulation of the real DOM and improving performance and the speed of the loading page.
- JSX Syntax: JSX which is an abbreviation for Javascript XML allows developers to write HTML-like code within JavaScript similar to what EJS (embedded Javascript) does thereby making component creation intuitive.
- Strong Ecosystem: A vast ecosystem of libraries and tools, such as Redux for state management and React Router for routing, enhances React's capabilities.
- Large Community: React boasts one of the largest and most active developer communities. This means extensive resources, tutorials, third-party libraries, and community support are readily available, making it easier to find solutions and stay updated with best practices.
**Strengths** =>
- Mature and Stable: With years of development and a large community, React is a stable and mature framework (wow, that I can't argue with... 11years and still counting is no joke).
- Scalability: React is highly scalable, suitable for both small projects and large, complex applications.
- Ecosystem: The extensive ecosystem provides solutions for virtually any problem you might encounter in frontend development.
**What are it's use cases** =>
React.js is ideal for large-scale applications that require a high level of interactivity and complex state management.
It's widely used in enterprise-level projects and popular applications like Facebook, Instagram, Airbnb and much more.
**SVELTE: The Compiler-First Framework**
Svelte was created by Rich Harris and it takes a rather radical approach to frontend development. Unlike traditional frameworks that do much of their work in the browser, Svelte shifts that work to compile time(sounds strange right?). This means Svelte applications are compiled into highly efficient, imperative code that updates the DOM.
**Svelte Key Features** =>
- No Virtual DOM: Unlike it's counterpart, Svelte eliminates the need for a virtual DOM by compiling components into efficient, imperative code.
- Reactive Assignments: Reactivity in Svelte is straightforward. By simply reassigning values it's compiler takes care of updating the UI.
- Minimal Bundle Size: The compiler approach results in smaller bundle sizes, enhancing performance.
- Ease of Learning: Svelte's syntax is intuitive and easy to grasp, making it a great choice for developers new to frontend frameworks.
Strengths:
- Performance: Due to Svelt having no virtual DOM overhead, it's applications are fast and efficient.
- Simplicity: The learning curve is gentle, and the framework's concepts are easy to understand.
- Conciseness: Less boilerplate code means faster development and cleaner codebases.
**What are it's use cases** =>
Svelte is ideal for projects where performance is critical and a lightweight framework is desired . I don't think it's ideal for Large applications that needs complex algorithm and UI, from my point of view it's perfect for small to medium-sized applications and static sites.
**HNG Internship: Gearing Up for Growth and Mastering React!** =>
At HNG, React is the technology of choice for frontend development. React's component-based architecture, extensive ecosystem, and strong community support make it an excellent choice for building dynamic and responsive web applications. My expections at HNG is to work on diverse projects that leverage React's capabilities to create user-friendly interfaces and innovative solutions.
My experience with React has been rewarding. Its declarative approach to UI development and robust state management solutions, like Context API and with it's large ecosystem, it has really empowered me to build applications with ease. I'm excited to contribute to HNG's projects, collaborate with talented developers, and continue honing my React skills.
To learn more about the HNG Internship program and its various offerings, check out the HNG internship Website @ {% embed https://hng.tech/internship %} and explore how HNG can help you hire top tech talent @ {% embed https://hng.tech/hire %}.
**My Conclusion** =>
Both React.js and Svelte offer unique advantages in the world of frontend development. React's component-based architecture and extensive ecosystem make it a robust choice for large-scale applications, while Svelte's compiler-first approach and simplicity make it a compelling option for performance-critical projects. Exploring these technologies opens up new possibilities and perspectives, enriching the developer experience.
Choosing the right technology depends on the specific needs of your project, and understanding the strengths of each framework is crucial. Whether it's React's mature ecosystem or Svelte's minimalist design, both frameworks push the boundaries of what's possible in frontend development.

1,903,958 | Welcome To QA Flex: Revolutionizing Your Quality Assurance Process! | QA Flex refers to a flexible approach to Quality Assurance (QA) in software development. This... | 0 | 2024-06-28T10:34:19 | https://dev.to/saumya27/welcome-to-qa-flex-revolutionizing-your-quality-assurance-process-47d8 | qa | QA Flex refers to a flexible approach to Quality Assurance (QA) in software development. This approach emphasizes adaptability, continuous improvement, and the integration of QA practices throughout the development lifecycle. QA Flex aims to ensure high-quality software by incorporating QA activities early and continuously, adapting to changing requirements, and leveraging automation and collaboration.
**Key Principles of QA Flex**
Early Involvement: QA is involved from the earliest stages of the project, including requirements gathering and design. This helps identify potential issues early and ensures that quality considerations are embedded throughout the development process.
Continuous Testing: QA Flex promotes continuous testing rather than treating testing as a separate phase. Automated tests are integrated into the development pipeline, enabling frequent testing and early detection of defects.
Automation: Automation is a cornerstone of QA Flex. Automated tests, continuous integration (CI), and continuous deployment (CD) pipelines help ensure that tests are run consistently and efficiently, reducing the risk of human error and speeding up the feedback loop.
Collaboration: QA Flex encourages collaboration between developers, testers, product owners, and other stakeholders. This collaborative approach helps ensure that everyone has a shared understanding of quality requirements and that feedback is incorporated promptly.
Adaptability: The QA process is adaptable to changing requirements and project dynamics. QA Flex acknowledges that requirements may evolve, and the QA approach should be flexible enough to accommodate these changes without compromising quality.
Focus on User Experience: QA Flex prioritizes the end-user experience. Testing scenarios are designed to reflect real-world usage, ensuring that the software not only meets functional requirements but also delivers a positive user experience.
**QA Flex Practices**
Shift-Left Testing: Testing activities are shifted to the left in the development timeline, meaning they start as early as possible. This includes reviewing requirements, participating in design discussions, and writing test cases early.
**Test Automation:**
Unit Tests: Automated unit tests verify the functionality of individual components or functions.
Integration Tests: Automated integration tests ensure that different modules work together as expected.
End-to-End Tests: Automated end-to-end tests simulate user interactions with the entire system to verify that it behaves as intended.
Continuous Integration/Continuous Deployment (CI/CD):
CI: Code changes are frequently merged into a shared repository and automatically tested.
CD: Successful builds from CI are automatically deployed to staging or production environments, ensuring that new features and fixes are delivered quickly and reliably.
Exploratory Testing: Manual testing is still valuable in QA Flex. Exploratory testing allows testers to use their creativity and experience to uncover issues that automated tests might miss.
Behavior-Driven Development (BDD): BDD involves writing test cases in a natural language format that describes the behavior of the system from the user's perspective. This practice helps ensure that all stakeholders have a clear understanding of the requirements and expected outcomes.
Performance Testing: Regular performance testing ensures that the software meets performance requirements and can handle expected loads.
Benefits of QA Flex
Higher Quality Software: By integrating QA throughout the development process, QA Flex helps catch defects early, reducing the risk of costly fixes later in the cycle.
Faster Time-to-Market: Automation and continuous testing enable faster feedback and quicker identification of issues, allowing for more frequent and reliable releases.
Improved Collaboration: Encouraging collaboration between different teams ensures that everyone is aligned on quality goals and helps build a culture of quality within the organization.
Enhanced User Satisfaction: Focusing on the end-user experience and continuously testing ensures that the software meets user needs and expectations.
Reduced Costs: Early detection and resolution of defects help reduce the overall cost of development and maintenance.
**Conclusion**
[QA Flex](https://cloudastra.co/blogs/qa-flex-revolutionizing-your-quality-assurance-process) is a modern approach to quality assurance that emphasizes flexibility, early and continuous testing, automation, collaboration, and a focus on user experience. By adopting QA Flex principles and practices, organizations can improve the quality of their software, accelerate delivery, and better meet the needs of their users. | saumya27 |

**Benefits of Private Blockchain Development**
Reduced Costs: Private blockchain development leverages smart contracts for automation, significantly reducing operational and administrative costs. Transaction fees are also lower as verification is limited to trusted nodes rather than all participants.
Enhanced Security: Access to a private blockchain is restricted to trusted parties, ensuring confidentiality and preventing sensitive information from becoming public. All stored data is cryptographically secured, enhancing overall network security.
Scalability: Private blockchains offer greater scalability and transaction throughput compared to public counterparts. They can handle more transactions and process larger volumes of data efficiently due to validation being limited to selected nodes with robust processing capabilities.
Improved Efficiency: With fewer participants, private blockchain networks experience reduced downtime and increased uptime. Nodes are better interconnected, and any faults are promptly addressed, ensuring smooth and efficient operations.
Control: Enterprises have full control over the infrastructure of a private blockchain, allowing for easier compliance with legal and regulatory requirements. Unlike public blockchains, the rules and governance of a private network can be adjusted by its administrators, enabling flexibility in transaction management and data governance.
**Our Private Blockchain Development Process**
Step 1: Select the Protocol
Choosing the right blockchain framework is crucial for creating a private blockchain. Options include leveraging an EVM-based protocol for Ethereum compatibility, utilizing the Substrate framework for streamlined development with extensive technical support, building on scalable ecosystems like Cosmos or Provenance, or forking an existing protocol.
Step 2: Build the Core Logic
After selecting the protocol, the core logic of the private blockchain is developed. This involves customizing existing logic, selecting a consensus algorithm, configuring transaction fees, upgrading header information, adjusting block height as needed, constructing pallets, implementing a permission module, and choosing appropriate file storage options.
Step 3: Development of the Logic
With the core logic defined, the development phase commences. This includes setting up a test network environment, finalizing file storage solutions, creating a genesis key store, determining the initial node count and their geographic distribution, and integrating APIs for seamless data exchange with external sources.
Step 4: Testing
Thorough testing on a dedicated test network is crucial before launching the main network. This phase involves validating faucet functionality, testing wallets, block explorers, and SDKs, and employing benchmarking and monitoring tools to assess performance, scalability, security, and network connectivity. Identified issues are addressed promptly to ensure a robust blockchain solution.
Step 5: Launch the Main Network
Upon successful completion of testing and issue resolution, the main network is launched. This marks the transition to a live environment where the private blockchain solution is operational and accessible.

The new paradigm ensures the exchange of how games are played, distributed, and experienced, providing many benefits to every sport's fan and developer.[ Cloud computing certification.](https://www.learnbay.co/cloud&devops/cloud-computing-online-course-training-institute) In this blog, we are going to find out what cloud gaming is, how it works, its benefits and challenges, and its doable impact on the future of gaming.
What is Cloud Gaming?
Cloud gaming, additionally regarded as gaming on demand or recreation streaming, is a science that allows game enthusiasts to play video games over the net unless they want effective hardware. Instead of jogging the recreation on a nearby device, the sport is hosted on far-off servers in information centers. The game's video and audio output are streamed to the player's device, while their input (such as keyboard, mouse, or controller actions) is dispatched again to the server.
How Does Cloud Gaming Work?
Cloud gaming operates through a combination of high-performance servers, fast internet connections, and advanced streaming technology. Cloud computing certification. Here is a simplified explanation of the process:
1. Gaming Hosting: The game runs on an efficient server in the records center. These servers are successful in handling disturbing games with high-end GUPs and CPUs.
2. Video and Audio Streaming: Servers broadcast the strategy of the sport and the video and audio output to the player's gadget in real-time. This system is comparable to how video streaming offerings such as Netflix or YouTube work, although with the complexity of real-time interactivity.
3. Player Input: The gamer machine captures their inputs (for example, pressing a button or moving the mouse) and sends these records back to the server.
4. Low Latency Communication: For cloud gaming to be effective, the conversation between the participants and the server wants to show up with minimum latency (delay). High-speed web connections and environmentally friendly data compression techniques are essential to achieve this.
Advantages of Cloud Gaming
Cloud gaming provides various benefits that can revolutionize the gaming industry:
1. Accessibility: One of the biggest advantages of cloud gaming is the ability to deliver premium games to a wide audience. Don't spend more money on an expensive game console or PC. Alternatively, users can play the new game on a variety of devices, such as low-end computers, tablets, and mobile phones.
2. Instant Play: it is not necessary to download or set up games when playing them on the cloud. Games can immediately get involved by watching sports on the cloud with today's technology, where video games can weigh tens or even several gigabytes, this convincing is very alluring.
3. Cross-Platform Play: players can play on one device and carry over their progress onto another without any issues due to cloud gaming services, which facilitate smooth cross-platform gaming. This adaptability improves the gaming experience and fits perfectly with the multi-decive lifestyle that people lead nowadays.
4. Reduced hardware obsolescence:
Players don't have to worry about their local hardware aging out because remote servers handle the computing work over time; this might result in significant cost savings because there is no longer a need to buy new gaming hardware to stay up to date with the newest titles.
5. Enhanced game development:
Developers now have more options thanks to cloud gaming, as they and make more difficult and intricate games without being constrained by the hardware of end users. As anticipated, cloud gaming reduces the need to optimize games for a variety of devices, which speeds up the production process.
Challenges of Cloud Gaming
Despite its potential, cloud gaming additionally faces countless challenges:
1. Internet Dependency: Cloud gaming requires a steady and high-speed net connection. In areas with negative web infrastructure, gamers can also experience trip lag, latency, and buffering issues, which can drastically affect the gaming experience.
2. Data Usage: Streaming high-definition video games can eat a lot of data, which may also be an issue for customers with restricted information plans or those living in areas with excessive record costs.
3. Latency: Even with the best technology, latency can never be eliminated. Competitive gamers, in particular, may find cloud gaming less attractive due to the moderate length of inputs, which is integral to fast-paced games.
4. Ownership and Licensing: Cloud gaming offerings typically operate on a subscription model, meaning gamers cannot personalize the video games they play. This raises questions about the acquisition and licensing of the sport, particularly if the carrier goes offline or removes the sport from the library.
The future of cloud gaming
In spite of these obstacles, cloud gaming seems to have a bright future. Large IT companies are making significant investments in cloud gaming infrastructure and services, including Google (stadia), Microsoft (iCloud), and NVIDIA (GeForce Now). Cloud computing certification. These investments
1. 5G and beyond: The rollout of 5G networks will significantly enhance net speeds and reduce latency, making cloud gaming more accessible to a wider audience. Future developments in the community's technological know-how should make the cloud gaming experience similarly beautiful.
2. Innovative Business Models: As the industry evolves, we may see new commercial industry fashions emerge. For example, cloud gaming offerings should offer a combination of subscription and pay-per-play options or advertising-supported free-to-play models.
3. Enhanced Integration: Cloud gaming should emerge additionally built-in with digital services, presenting seamless transitions between gaming, social media and content material consumption. It may want to create a digital ecosystem that is more integrated and engaging for users.
4. Increased Competition: As more corporations enter the cloud gaming market, the opposition will demand innovation and lower fees for consumers. This can lead to more services, a wider range of suitable games, and extra pleasant prices.
Conclusion
Cloud gaming is all set to revolutionize the gaming industry.
It makes exceptional gaming easy, extra comfortable, and flexible.
There are challenges to overcome; however, the benefits that can be made are significant.

1,903,948 | Why Typescript is better than JavaScript | Why TypeScript is Better than JavaScript The world is evolving and so is advanced... | 0 | 2024-06-28T10:25:17 | https://dev.to/heythematic/why-typescript-is-better-than-javascript-2d2i | javascript, typescript, programming, coding |
## Why TypeScript is Better than JavaScript
The world is evolving and so is advanced technology and tools. Back in the day, JavaScript used to be on every website, providing responsiveness to pure HTML-CSS websites. However, as web development becomes more complex, JavaScript alone sometimes falls short in terms of maintainability and scalability. This is where TypeScript comes into play, offering a range of features that enhance the development experience and help manage large codebases more effectively.
### 1. **Static Typing**
One of the most significant advantages of TypeScript over JavaScript is its static typing. Static typing means that type checking is done at compile time rather than at runtime. This feature helps catch errors early in the development process, reducing the likelihood of runtime errors. By defining types for variables, function parameters, and return values, developers can write more predictable and bug-free code.
```typescript
let message: string = "Hello, TypeScript";
message = 42; // Error: Type 'number' is not assignable to type 'string'.
```
### 2. **Improved Tooling and Editor Support**
TypeScript's static type system allows for better tooling and editor support. IDEs and code editors like Visual Studio Code offer powerful features such as autocompletion, refactoring tools, and real-time error detection. These tools enhance the developer experience, making it easier to navigate and manage large codebases.
### 3. **Enhanced Code Maintainability**
Maintaining and scaling large JavaScript projects can be challenging due to the language's dynamic nature. TypeScript addresses this issue by enforcing a more structured and consistent codebase. The explicit types and interfaces in TypeScript make the code more readable and easier to refactor, which is especially beneficial for teams working on long-term projects.
### 4. **Compatibility with JavaScript**
TypeScript is a superset of JavaScript, which means any valid JavaScript code is also valid TypeScript code. This compatibility allows developers to gradually adopt TypeScript in existing JavaScript projects. They can start by renaming `.js` files to `.ts` and incrementally add type annotations and other TypeScript features. This seamless integration makes the transition to TypeScript smooth and less disruptive.
### 5. **Better Error Handling**
TypeScript's type system helps catch errors at compile time, but it also improves runtime error handling. By using features like `never` type and exhaustive type checks, developers can ensure that all possible code paths are handled. This leads to more robust and reliable applications.
```typescript
type Fruit = "Apple" | "Banana";
function getFruitColor(fruit: Fruit): string {
switch (fruit) {
case "Apple":
return "Red";
case "Banana":
return "Yellow";
default:
const exhaustiveCheck: never = fruit;
throw new Error(`Unhandled case: ${exhaustiveCheck}`);
}
}
```
### 6. **Active Community and Ecosystem**
TypeScript has a vibrant and growing community. Many popular frameworks and libraries, such as Angular and Vue.js, are written in TypeScript or offer strong TypeScript support. This widespread adoption means that developers have access to a wealth of resources, including documentation, tutorials, and community-driven tools, making it easier to learn and use TypeScript effectively.
**Conclusion **
While JavaScript remains a powerful and widely-used language, TypeScript offers several compelling advantages that make it a better choice for many projects. Its static typing, enhanced tooling, improved maintainability, and seamless compatibility with JavaScript make it an excellent option for developing robust and scalable web applications. As the TypeScript community continues to grow, its benefits will become even more pronounced, solidifying its place as a superior alternative to JavaScript.

1,903,947 | Minimization of Finite Automata | Finite Automata (FA) serve as essential computational models in computer science and formal language... | 0 | 2024-06-28T10:23:54 | https://dev.to/pushpendra_sharma_f1d2cbe/minimization-of-finite-automata-4ccb |
Finite Automata (FA) serve as essential computational models in computer science and formal language theory. They are pivotal in the design of digital circuits, lexical analyzers, and systems requiring pattern recognition and state management. However, finite automata may become excessively large, leading to inefficiency. Minimization of finite automata addresses this issue by reducing the number of states without compromising their ability to recognize languages. This discussion explores the principles, techniques, and advantages of finite automata minimization.
## Understanding Finite Automata
Before diving into the minimization process, it’s essential to understand what finite automata are. There are two main types:
1. **Deterministic Finite Automata (DFA)**: In a DFA, each state has exactly one transition for each possible input symbol.
2. **Non-deterministic Finite Automata (NFA)**: In an NFA, a state can have zero, one, or multiple transitions for each input symbol.
## Why Minimize Finite Automata?
[Minimizing finite automata](https://www.tutorialandexample.com/minimization-of-finite-automata) is essential for several reasons:
- **Efficiency**: Smaller automata are faster and require less memory, making them more efficient for implementation in software and hardware.
- **Simplicity**: Simplified models are easier to understand and debug.
- **Cost Reduction**: In hardware applications, fewer states can lead to reduced manufacturing costs.
## Steps for Minimizing Finite Automata
### 1. Remove Unreachable States
An unreachable state is a state that cannot be accessed from the initial state through any sequence of inputs. Such states have no impact on the language recognized by the automaton and can be removed without affecting its functionality.
**Algorithm**:
- Start from the initial state and mark it as reachable.
- Recursively mark all states that can be reached from any already reachable state.
- Remove all states that are not marked as reachable.
### 2. Remove Dead States
A dead state is defined as a state from which it is impossible to reach any accepting state. Such states are non-contributory towards the acceptance of strings and can therefore be eliminated.
**Algorithm**:
- Mark all accepting states.
- Recursively mark any state that leads to an already marked state.
- Remove all states that are not marked.
### 3. Merge Equivalent States
Two states are considered equivalent if they cannot be distinguished by any sequence of inputs. In other words, for any input sequence, both states either both end up in accepting states or both end up in non-accepting states.
**Algorithm** (Partitioning Method):
1. **Initialization**: Partition the states into two groups: accepting and non-accepting states.
2. **Refinement**:
- Split each group based on whether the states transition to different groups on a given input symbol.
- Repeat until no more splits are possible.
3. **Merge**: Combine all states in the same group into a single state.
### Example
Consider a DFA with states {A, B, C, D}, where A is the initial state, and D is the accepting state. The transition function is as follows:
- From A: 0 → B, 1 → C
- From B: 0 → D, 1 → A
- From C: 0 → A, 1 → D
- From D: 0 → D, 1 → D
**Step-by-step Minimization**:
1. **Remove Unreachable States**: All states are reachable from the initial state A.
2. **Remove Dead States**: State D is an accepting state, so it is not dead. All other states lead to D directly or indirectly.
3. **Merge Equivalent States**:
- Initial partition: {A, B, C} (non-accepting), {D} (accepting).
- Refinement based on transitions:
- From {A, B, C} on input 0: {B, A}, {C}.
- From {A, B, C} on input 1: {C, A}, {B}.
- Further refinement shows that B and C transition similarly, so they remain separate from A.
- Final states: {A}, {B}, {C}, {D}.
After merging equivalent states, the minimized DFA has the same structure, showing that sometimes no further minimization is possible if the original DFA is already minimal.
## Benefits of Minimization
- **Performance Improvement**: Smaller automata result in faster processing times.
- **Reduced Complexity**: Simplifies the design and implementation of algorithms and systems.
- **Resource Optimization**: Conserves memory and computational resources, which is critical in embedded systems and hardware implementations.
## Conclusion
The minimization of finite automata is key to enhancing computational models for greater efficiency and simplicity. It involves eliminating unreachable and redundant states, as well as consolidating states that are equivalent, thus reducing the automaton's size without compromising its function. This process results in improved performance, streamlined implementation, and reduced costs in real-world applications. Mastery of these minimization techniques is vital for professionals in areas related to formal languages and automata theory. | pushpendra_sharma_f1d2cbe | |
